JP2002204710A - Canopy cloth for simple umbrella - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a canopy cloth for use in an umbrella capable of simply unfolding the canopy cloth by movement for raising a ring runner along an umbrella stick in a direction from a downside of the stick and folding the same by movement in a direction from an edge side (a ferrule) of the stick. SOLUTION: In a conventional umbrella structure, the canopy cloth is tightly expanded by a method wherein at a time of unfolding, strong force raising the ring runner supporting stretchers from a lower spring to an upper spring along the umbrella stick travels across umbrella ribs to make the umbrella ribs arched and the canopy cloth brought into close contact with the umbrella ribs tightly expanded. A simply structured umbrella eliminating parts used in the conventional umbrella structure has weak raising force even if the conventional cloth is used, hardly making the canopy cloth tightly expanded. A material having a purpose for expanding the canopy cloth itself and requisites necessary for the canopy cloth is utilized and used to solve the problems in the simply structured umbrella.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a simple structure such as a disposable umbrella which can be easily expanded and contracted by applying a small force as compared with the conventional umbrella cloth, thereby simplifying a structural member for expanding the conventional umbrella cloth. Related to the practical use of a structure umbrella.

[0002]

2. Description of the Related Art A conventional umbrella cloth is made of a cloth which is resistant to water but has no particular characteristics. Compared to the conventional umbrella structure, the strong force that pushes up along the umbrella axis to the upper umbrella is transmitted to each umbrella bone, making it possible to make the umbrella bone into a bow and expand the umbrella cloth that adheres at the same time and stretch it with a pea There has been no proposal of an umbrella cloth suitable for an umbrella having a simple structure in which a stretcher (a receiving bone) and a runner (a potter's wheel) are omitted and a strong force cannot be transmitted to such an umbrella bone when opening and closing the umbrella. .

[0003]

The most important function of the umbrella is how the umbrella cloth can be expanded when the umbrella is opened. It is necessary to have parts such as lower runner (rotary wheel), stretcher (bone receiving), etc., which can be opened and closed by opening and closing by operation from the direction. There are many problems that various materials need to be used to make the most suitable material for the umbrella fabric that can be easily shrunk, durable, resistant to water, and light and thin.

[0004]

The present invention can be used in a wide variety of fields, including medical products such as condoms, which can be easily expanded and contracted by applying a slight force compared to conventional umbrella fabrics, and are durable, water-resistant and light and thin. By using materials such as synthetic resin polyurethane as umbrella cloth, it is possible to use umbrella bones even for umbrellas with a simple structure that does not require members such as lower runners (runners), stretchers (receivers), etc. The fabric was able to expand with peen just by opening it, which solved the problem.

[0005]

Embodiment 1 An embodiment of the present invention will be described with reference to FIG. When the umbrella cloth 6 is opened, an object 12 made of acrylic, wooden or the like is adjusted to the width and length of the umbrella bone 6 when the umbrella bone 6 is opened.
Then, the umbrella cloth 7 is expanded for each width of the umbrella bone 6, and the object 12 is attached to a portion where the umbrella cloth 7 comes into close contact with the umbrella bone 6.

While the umbrella cloth 7 to which the object 12 is attached is expanded, the object 12 attached to the umbrella cloth 7 is sequentially bonded and bonded to the upper part of each umbrella bone 6, and the umbrella cloth 7 is stretched over all the umbrella bones 6.

By fixing and attaching the umbrella cloth 7 to the umbrella bone 6 by such a method, a slight force of the umbrella cloth 7 can be applied to facilitate the expansion and contraction of the umbrella cloth 7. It is possible to provide an easy-to-use umbrella that prevents unnecessary movement such as vertical movement of the fabric itself when opening and closing the umbrella and when carrying the umbrella.

[0008]

Embodiment 2 An embodiment of an umbrella having a simple structure using the present invention will be described with reference to FIG.

A simple structure in which the umbrella shaft 1 and the umbrella bone 6 are made of wood by using the ring runner (rotary wheel) 8 instead of the stretcher (reception bone) instead of the conventional umbrella structure and replacing it with a runner (wheel) Umbrella.

A ring runner (rotary wheel) 8 is made of a hard material such as acrylic and has a thickness of about 1.5 mm to 2 mm. The center is a hole 10 through which the umbrella shaft 1 is passed. When the umbrella is closed by applying 11, the umbrella shaft 1 is located at the upper part of the stop gutter 2.

[0011] In addition, the umbrella shaft tip stone projection 4 above the undulating projection 3
The part of the umbrella shaft 9 leading to the upper part is gradually thickened toward the upper part, and when the ring runner (the potter's wheel) 8 opens the umbrella, the umbrella is moved from the lower part to the upper part of the undulating projection 3 along the umbrella axis 1. The umbrella can be opened by raising the bone 6.

As described above, in order to stabilize and maintain the opened state of the umbrella, the rubber edge burr 11 provided around the hole of the ring runner (rotary wheel) 8 at the part of the umbrella shaft 9 is strong against the umbrella shaft 9. And the opened umbrella bone 6 can be kept intact without the ring runner (spotter) 8 falling out.

The umbrella bone 6 is fixed to the umbrella shaft tip foot 4 and the fulcrum hinge 5 of the umbrella bone 6 so as to move up and down, and the umbrella cloth 7 is applied to the entire upper part of the umbrella bone 6 by the method described in the first embodiment. With the upward movement of the umbrella bone 6, the umbrella cloth 7 is pulled and the slight force of the umbrella bone 6 is completely opened, so that the umbrella cloth 7 according to the present invention can be expanded with peen.

In such an umbrella having a simple structure, even when an umbrella cloth used in a conventional umbrella and a thinner cloth are used, the gravitational force of the cloth on the umbrella bone is larger than expected, The umbrella member to be used cannot withstand the gravitational force of the entire fabric when the umbrella is opened and closed. .

[0015]

Most of the umbrellas conventionally used are made of metal except for fabrics and patterns, and runners (rolling wheels) that support a stretcher made of metal are supported from bottom to top. If the strong force pushing up along the umbrella axis is transmitted to each umbrella bone and it is strong against water, it can expand the umbrella cloth sufficiently regardless of the expansion and contraction of the fabric slightly, but in the umbrella of simple structure Due to its structure, it is made of wood, paper, etc. from its use, so it can be easily expanded and contracted by applying a slight force, and it is strong, water resistant, light and thin material used as umbrella cloth The present invention satisfies all of these conditions, and the present invention utilizes all of these conditions as a fabric for umbrellas, so that a simple umbrella and members without a stretcher (bone receiving) runner (potter's wheel) can be entirely made of wood or paper. Etc. Use the umbrella is the umbrella fabric was even able to put a ping the fabric if in the umbrella can be easily extended Kasakotsu even open operations, such as.

According to the present invention, an umbrella and a wooden having a simple structure,
Umbrellas of various structures can be provided that are low in cost, low in cost, pollution-free and convenient, such as a compact umbrella with a shorter umbrella shaft than conventional umbrellas using members made of paper or the like.
