2. Description of the Related Art Generally, this kind of umbrella is, for example,
As shown in JP-88116-A, sunshine is blocked by an umbrella cloth stretched over the ribs, and conventionally, woven fabrics such as cotton and hemp and lace fabrics are often used as umbrella fabric materials. .

[0003]

In the conventional umbrella of this type, the umbrella cloth usually does not have a see-through property in order to obtain the function of blocking the sunshine. It is difficult to obtain a sufficient cool breeze when using in summer, because the umbrella cloth does not have sufficient air permeability. There is also a problem that the wind breaks and the umbrella bone is inadvertently damaged.

[0004] The present invention has been developed in view of the above circumstances, the purpose is to be able to accurately see the distance through an umbrella cloth while reliably blocking the sunshine, In addition, the goal is to provide an umbrella with an excellent cool breeze.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a rib 3 is supported on an umbrella shaft 1 so that it can be opened and closed, and an umbrella cloth 4 is stretched on the rib 3. Umbrella, the umbrella cloth 4 is formed in a net shape having a large number of through holes 7,
The reflectance of light on the front surface of the umbrella cloth 4 is increased, and the reflectance of light on the back surface of the umbrella cloth 4 is reduced.

A waterproof sheet 8 covering the surface of the umbrella cloth 4 may be made detachable from the umbrella cloth 4 described above.

[0007]

According to the first aspect of the present invention, the umbrella cloth 4 is formed in a net shape having a large number of through holes 7 and is excellent in air permeability or ventilation, so that the umbrella cloth even when a strong wind blows. For example, the wind does not flow into the umbrella 4 and the wind passes well from inside the umbrella to inside the umbrella. Further, for example, direct sunlight is surely reflected on the front side of the umbrella cloth 4 and hardly penetrates into the back side of the umbrella cloth 4, and furthermore, the reflectance of light on the back side of the umbrella cloth 4 is low. On the back side of 4, the reflection of light is suppressed, and the surrounding light hardly enters the eyes of the person wearing the umbrella.
You can clearly see the surrounding scenery and situation.

Further, according to the first aspect of the present invention, even if another person tries to look inside the umbrella from the outside of the umbrella through the through hole 7 of the umbrella cloth 4, the light reflectance on the surface side of the umbrella cloth 4 is high. Therefore, the face of the person wearing the umbrella or the like can be prevented from being seen by others. According to the second aspect of the present invention, it is possible to use it as an umbrella simply by attaching the waterproof sheet 8 to the surface of the umbrella cloth 4.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An umbrella shown in FIG. 1 is a so-called sun umbrella used to block sunlight, and has a handle 2 on one end of an umbrella shaft 1 and a plurality of ribs on the other end. 3 has a known structure in which an umbrella cloth 4 is stretched over the main rib 3. In the drawing, reference numeral 5 denotes a wheel that is slidably inserted into the umbrella shaft 1, reference numeral 6 denotes a supporting bone that connects the wheel 5 to the intermediate portion of the rib 3 in the longitudinal direction, and reference numeral 10 denotes a stone provided at the tip of the umbrella shaft 1. Show.

In the above construction, according to the present invention, the umbrella cloth 4 stretched over the rib 3 is formed in a net shape having a large number of through holes 7 to increase the light reflectance of the surface of the umbrella cloth 4 and Thus, the light reflectance of the back surface of the umbrella cloth 4 is reduced. That is, in the embodiment shown in the figure, the umbrella cloth 4 is formed from a black-dyed mesh cloth formed by knitting synthetic fibers as shown in FIG. 3, and the inner diameter S of the through hole 7, in other words, the size of the mesh is approximately 1.8
mm.

An umbrella cloth 4 made of the above mesh fabric
Silver is vapor-deposited only on the front side of the umbrella cloth 4 to increase the light reflectance on the front side of the umbrella cloth 4, while the back side of the umbrella cloth 4 is kept black in mesh cloth, The light reflectance on the back side is reduced. In the embodiment shown in the figure, a waterproof sheet 8 made of vinyl chloride having substantially the same shape as the umbrella cloth 4 is separately formed, and a cap 81 that can be fitted to the tip of the rib 3 is provided on the outer periphery of the waterproof sheet 8. The waterproof sheet 8 is detachably attached to the surface of the umbrella cloth 4 by fitting a plurality of caps 81 to the ribs 3 of the cap 81,
The surface of the umbrella cloth 4 can be covered with the waterproof sheet 8.

Thus, when the above umbrella is used as a parasol, the umbrella is used without the waterproof sheet 8 attached.
Since the umbrella cloth 4 is formed from a mesh cloth and has a large number of through holes 7, it has good air permeability or air permeability, so that a cool breeze feeling can be obtained. Since there is no wind, it is possible to prevent the umbrella from being inadvertently blown by the strong wind, or to prevent the ribs 3 and the support bones 6 from being damaged.

In addition, strong sunlight is reliably reflected on the front side of the umbrella cloth 4 having high light reflectance, and is reliably shielded from light by the umbrella cloth 4 almost without being inserted into the back side of the umbrella cloth 4. It effectively fulfills the function of a parasol. Further, since the reflectance of light on the back side of the umbrella cloth 4 is low, reflection of light on the back side of the umbrella cloth 4 is suppressed, and ambient light may enter the eyes of the person wearing the umbrella. Since there is almost no umbrella, it is possible to clearly see the surrounding scenery and situation through the umbrella cloth 4 with the umbrella, and therefore, for example, when playing golf in a day with strong sunshine, the umbrella is put on the launched golf ball. By looking through the umbrella cloth 4 from the point of contact, even a flying ball can be chased with eyes.

On the other hand, for example, an umbrella cloth 4
To see the inside of the umbrella through the through hole 7 of the umbrella cloth 4
Since the reflectance of the light on the surface side of the umbrella cloth 4 is high, and the light reflected on the surface side of the umbrella cloth 4 is dazzling when inserted into the eyes of another person, the face of the person wearing the umbrella, for example, inside the umbrella from the other person Etc. are difficult to see, and the privacy of the person wearing the umbrella is protected.

On the other hand, if it is raining, for example, the waterproof sheet 8 is simply put on the front side of the umbrella cloth 4 and the cap 81 is fitted to the tip of the rib 3. 4
Can be reliably blocked rainwater by the waterproof sheet 8 and can be used immediately as an umbrella. In the above embodiment, the reflectance of light on the front side of the umbrella cloth 4 is increased by vapor-depositing silver on the front side of the umbrella cloth 4, but the present invention is not limited to this. For example, aluminum is vapor-deposited. Alternatively, the surface of the umbrella cloth 4 may be colored with a color having a high light reflectance such as gold or white with a dye or the like to increase the light reflectance of the umbrella cloth 4 on the surface side.

Further, in the above embodiment, the back side of the umbrella cloth 4 is kept black of the mesh cloth, but it may be colored by a dye or the like into a color having a low light reflectance such as dark blue. In the above embodiment, the umbrella cloth 4 is formed from a mesh fabric formed by knitting synthetic fibers. However, the present invention is not limited to this. For example, a large number of through holes are formed in a synthetic resin sheet by punching. What was formed in the shape of a net may be used.

In the above embodiment, the inner diameter of the through hole 7 is set to about 1.8 mm. However, the present invention is not limited to this, and an appropriate size such as 1.5 mm or 2.5 mm is selected. The shape of the through hole 7 may be arbitrarily changed. The above umbrella can be applied to, for example, a beach umbrella or a golf umbrella.

[0018]

As described above, according to the first aspect of the present invention, the umbrella cloth 4 has good air permeability or air permeability, so that a cool sensation can be obtained, for example, even when strong wind blows. 4
The umbrella can be prevented from being inadvertently blown off by the wind, and the sun can be reflected on the front side of the umbrella cloth 4 without fail. Since it is hardly inserted into the umbrella cloth, it functions effectively as a parasol, and furthermore, the reflectance of light on the back side of the umbrella cloth 4 is low, and reflection of light on the back side of the umbrella cloth 4 is suppressed. Therefore, ambient light hardly enters the eyes of the person wearing the umbrella. Therefore, the surrounding scenery, situation, and the like can be clearly seen through the umbrella cloth 4 while the umbrella is being worn.

Further, according to the first aspect of the present invention, even if another person tries to look inside the umbrella through the through hole 7 of the umbrella cloth 4 from outside the umbrella cloth 4, the light reflectance on the surface side of the umbrella cloth 4 is high. Therefore, it is difficult for others to see the inside of the umbrella, for example, the face of the person wearing the umbrella, and the privacy of the person wearing the umbrella can be protected. According to the invention described in claim 2,
By making the waterproof sheet 8 covering the surface of the umbrella cloth 4 detachable from the umbrella cloth 4, the waterproof sheet 8 can be immediately used as a rain umbrella just by attaching the waterproof sheet 8 to the surface of the umbrella cloth 4, and it is easy to use. This increases the versatility of the umbrella.
