Metals are used for general umbrella construction materials from the viewpoint of strength, but it is dangerous if the tip of the umbrella (dewpoint) hits people, and it is necessary to separate vinyl and metal when discarding For this reason, many air umbrellas have been proposed as means for solving this problem. (For example, see Patent Documents 1 and 2)

In addition, it is a large-sized simple tent used for sunshade and rain protection, etc., to reduce the weight of metal members and to suppress the increase in manufacturing cost, tension is applied in the outer diameter direction of a generally circular sheet. There is a structure in which a plurality of elastic rod-like members to be applied are inserted and the sheet is suspended on a branch of a standing tree or the like via a suspension provided at the center of the sheet. (See Patent Document 3).

Registered Utility Model No. 3072661 (see FIG. 1) Japanese Utility Model Publication No. 54-168963 (see FIG. 1) JP 2011-184890 A (see FIG. 1)

  According to the pneumatic umbrella of the above-mentioned utility model document 1, the basic bone or cloth of the basic structure is formed of a tubular thermoplastic film. In claim 1 of the utility model document 1, it is simply stated that “the umbrella body is kept open by the air being taken in and out”, and the method of constructing the umbrella is not known in detail, but in the sentence of claim 2 There is a description that “a frame is formed by press-fitting air into the tube-shaped hollow portion, and so on”, and in the specification 0009, the umbrella is configured by combining at least the bones of the tube. In the frame structure using a tube, there is a problem that manufacturing is complicated and strength is weak.

Patent Document 2 describes a boneless pneumatic umbrella.
With reference to FIG. 7, the boneless pneumatic umbrella described in this patent document will be described. This boneless pneumatic umbrella has an umbrella body in which an annular air bag having an air plug is attached to the edge of the umbrella membrane, an umbrella pattern bag that supports the umbrella body in the lower part thereof, and a plurality of tension yarns on the periphery of the umbrella body. It is a pneumatic umbrella in which one end is attached and the other end is attached to a position below the umbrella body of the umbrella pattern bag, and the annular air bag is supported by a tension thread.
There is no description of special features etc. about the air bag attached to the edge of the umbrella membrane,
General air bags are not so high in air pressure, so the tension is weak. Therefore, it is necessary to increase the diameter of the air bag, etc. There is a problem that handling is complicated, such as getting involved in the hand.

According to the simple tent of Patent Document 3 above, the basic structure is composed of a stretchable fabric cloth sheet, a glass fiber reinforced plastic elastic rod-shaped member, or a connecting member such as aluminum. The elastic rod-shaped member is a rod-shaped member. The elastic rod-shaped member is divided for insertion into the insertion portion, and handling is troublesome.

  Accordingly, the present invention has been made to solve such a potential problem of the conventional technology. In a tube having a complicated shape corresponding to the main frame of an umbrella, there are many connection portions of the tube, and air leakage occurs. Because it is difficult to raise the air pressure because it is easy to cause, the idea of a method that eliminates the need for the frame of the tube, the idea of eliminating the need to support the umbrella body with a tension thread, and elasticity in a simple tent The purpose is to increase convenience and use points by reducing the complexity of inserting the rod-shaped member into the rod-shaped member insertion portion and further reducing the weight.

In order to achieve the above object, the shield according to the first aspect of the present invention comprises:
At least one side is attached to a sheet having a shape of a straight line or a curve, or both by bending a part of the outer peripheral edge of the sheet or the entire periphery thereof,
The opening at both ends of the hose is closed to provide a fluid introduction port at a predetermined location, and when the fluid is press-fitted from the fluid introduction port, a force that swells and forms a straight line due to the pressure of the fluid acts to The sheet having the predetermined shape is formed by stretching.

The shielding body according to the second aspect of the present invention forms a hollow continuous bag body by folding a part or the entire circumference of the outer peripheral edge of a sheet having at least one of a straight line and / or a curved line inside. , it is inserted so as to bend the straight hose having a fluid inlet port midair by closing the opening at both ends at predetermined positions of the bag body, when the fluid is pressed into the hose, the fluid The sheet is stretched by the pressure of the pressure and becomes a straight line, and the sheet is stretched to form the sheet having the predetermined shape.

  According to a third aspect of the present invention, there is provided the shield according to the present invention, wherein the hose is provided with a switching valve directly at a fluid inlet provided at a predetermined position of the hose or via a fluid inlet tube at the fluid inlet. It is characterized by being.

Fourth shielding system using the shield embodiment of the present invention, using a third shield of the embodiment, through the switching valve attached to the hose, the fluid press-fitting device for pressing the fluid Or a fluid press-fitting / drawing device is connected.

  The shielding system using the shielding body according to the fifth aspect of the present invention includes a fluid introduction port provided at the predetermined location of the hose, or between the fluid introduction port and the fluid press-fitting device. The pressure gauge is connected.

According to the shielding system of the present invention, a linear hose is bent to a part of or the entire circumference of the outer peripheral edge of the sheet on a sheet having a predetermined shape having at least one side of a straight line, a curved line, or both. Mounting,
The opening at both ends of the hose is closed to provide a fluid introduction port at a predetermined location, and when the fluid is press-fitted from the fluid introduction port, a force that swells and forms a straight line due to the pressure of the fluid acts to Since the shield is used, the sheet having the predetermined shape is formed.
When used for a portable umbrella, a strong tension is generated in the outer diameter direction, so that the seat functions as a substitute for the conventional function of the main bone, and therefore, a frame of the tube corresponding to the main bone becomes unnecessary.

Furthermore, not only the main bone but also the middle bone for supporting the main bone that was conventionally provided at the center of the umbrella is not required, and it is only necessary to provide a handle for supporting the seat instead of the middle bone, and the ultimate simple structure. It becomes a portable umbrella, and it is possible to reduce the cost.
Also, various shapes such as circular and semicircular shapes can be manufactured.

Further, according to the shielding system of the present invention, as in a large-sized simple tent, a strong tension is generated in the outer diameter direction by strengthening the pressure input to the linear hose, and the hose replaces the elastic rod-shaped member. This eliminates the complexity of inserting and connecting a conventional elastic rod-like member to the rod-like member insertion portion. As a result, in the present invention, the use is expanded due to further enlargement, weight reduction, and convenience. Can be planned.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment shown below exemplifies a shielding system for embodying the technical idea of the present invention, and is not intended to specify the present invention, and is included in the scope of the claims. It is equally applicable to those of other embodiments.

With reference to FIG. 1, the structure of the shielding body which concerns on embodiment of this invention and this shielding body is demonstrated. FIG. 1 is a plan view and a cross-sectional view of the shield 1 according to the embodiment of the present invention.

The shield 1 of the present invention is attached to a substantially semicircular sheet 2 by bending a straight hose 3 with the openings at both ends closed to the substantially semicircular portion of the outer peripheral edge of the sheet 2. A fluid is press-fitted through a fluid inlet 31 provided at a predetermined location.
Due to the pressure of the fluid, a force that swells and forms a straight line works, and the sheet 2 is stretched to form the shield 1 having the predetermined shape.

The most significant feature of the present invention is that the linear hose 3 attached to the seat 2 in a substantially semicircular shape generates a strong elastic restoring force to return to the linear shape by press-fitting the fluid. The restoring force works in the outer diameter direction of the sheet 2 to form the shield 1 having a strong plane maintaining force.
The material of the sheet 2 is excellent in flexibility, weather resistance, and impact resistance, and a thermoplastic film or woven fabric that can be folded in a small volume is suitable.
On the other hand, the hose 3 is suitably made of woven fabric, rubber or synthetic resin whose inner surface is gas-sealed.

In FIG. 2, it is the structure of the shielding system 4 using this shielding body 1. FIG.
Shield 1 composed of a linear hose 3 for press-fitting a fluid such as air, a pressure gauge 10 connected to the hose 3 via a fluid introduction tube 12, a fluid switching valve 11, and a fluid for controlling the fluid In the control device 12, the configuration of the fluid control device is a fluid press-fitting device or a fluid press-fitting / drawing device.

FIG. 3 is a cross-sectional view of the linear hose 3 provided on the outer peripheral edge of the sheet 2 according to the form. FIG. 3A is a diagram in which the hose 3 is directly attached to the outer periphery of the semicircular sheet 2. Adhesive suitable for the material of the hose and sheet used is good.

In FIG. 3b, since the semicircular portion of the outer peripheral edge of the sheet 2 is folded inward to provide a hollow continuous bag body, the adhesive method of the woven sheet can be strongly joined by sewing.
This makes it possible to apply a strong pressure to the linear hose 3 inserted into the bag, and is a method suitable for a large tent or event playground equipment that requires a large tension.
Further, even when an adhesive is used regardless of the sewing, the adhesive most suitable for the sheet material can be used because the sheets become sheets.

FIG. 4 shows a simple umbrella 6 in which a handle 51 is attached to a shield 1 in which a straight hose 3 is attached to a substantially circular sheet 2 on the entire circumference, FIG. 2a is a plan view in a stretched state, and FIG. It is sectional drawing when cut | disconnecting by b '.
A conventional umbrella has a structure in which a core bone opens and a seat is stretched with a central bone as a core. However, if the shield 1 that provides strong tension according to the present invention is used, the handle 51 is directly attached to the hose 3 of the shield 1. Even if attached, the shape of the umbrella will not collapse.

With such an umbrella, there are few members to use, the structure is simple, and it can be manufactured at low cost. In addition, it is safe for the user to hit another person, has a light weight, and has an advantage that the shield 1 can be made small because the person puts it in the center.
The method of binding the shield 1 and the handle 51 allows the hook-and-loop fastener to be easily removed, so that the shield 1 and the handle 51 can be enjoyed in various ways or when the shield 1 becomes unusable. Is easy to do.
It is said that vinyl umbrellas that have become unusable due to winds such as typhoons are thrown away at stations, etc., and station staff are struggling with the separation of vinyl and metal fittings. Just remove and throw away.
Further, the convenience can be improved, for example, by incorporating the fluid control device 12 or the like for expanding the shield 1 into the handle 51.

FIG. 5 shows an example of a large, substantially circular simple tent 7.
5A is a plan view when the large simple tent 7 is extended, and FIG. 5B is a side view.
The simple tent 7 is substantially circular, and a linear hose 3 is attached in an annular shape.
In order to fix the tent 7, the column 52 is attached to the center of the seat and the rope 53 is attached to several places of the hose 3.
In the method of connecting the elastic rod-shaped members in a ring shape as in the previous case 2, handling is complicated, including the storage of the elastic rod-shaped members and the coupling tools, the weight is high, the cost is high, and the enlargement is particularly difficult.

In the present invention, the outer peripheral edge of the sheet 2 is folded inward to provide a hollow communicating bag body, and it becomes possible to apply a strong pressure to the fluid press-fitted into the linear hose 3 inserted into the bag body. Tents can be easily and at low cost.

FIG. 6 shows an automobile awning tent 8, FIG. 6 a is a plan view thereof, and FIG. 6 b is a side view thereof.
The conventional automobile cover does not have the function as an awning tent because the air heated by the roof to wrap up the automobile body is not dissipated and heat is not convected outside the vehicle window so that it is stored inside the car.
Even if a simple awning tent for an automobile having such a function is manufactured, a hard support such as a metal must be used, and there is a problem that the weight and handling are troublesome.

The automobile awning tent 8 according to the present invention can flatly extend the upper surface of the automobile flatly, so that a plane space is formed between the tent and the bonnet, so that convection of hot air is likely to occur and high temperature can be prevented.
When the stretch strength is weak due to the large shielding area, a concentric small oval hose can be attached inside the hose 3 for reinforcement. In addition, since no metal or the like is used for the constituent material, the automobile is not damaged, the handling is simple, and it can be manufactured at low cost.

Shielding systems can be used as portable rain / shade caps for small ones, as portable simple umbrellas, and for automobile sunshades, large portable rain / shade tents, and playground equipment. I'm confident.
