As a net structure, it is important to provide a nonwoven net wherein horizontal and longitudinal axes 1, 2 forming the net cross each other. As the material of the outer bag, various material qualities, for example, polypropylene, nylon, a synthetic resin excellent in tenacity commercially available for a vacuum pack or the like can be suitably used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a vacuum formed by a combination of specially shaped nets, which is plastic in the normal state and can be quickly made into a solid plate by applying a vacuum, so that it can be used for various purposes. It concerns a solid plate.

[0002]

2. Description of the Related Art It is relatively new that vacuum-assisted devices have been used in people's lives and customs.

Among them, the vacuum pack is the most popular and a very useful packaging means. This vacuum pack plays a role of blocking the foods in the packaging container from the outside air by using a vacuum to prevent oxidation and decay.

At this time, it should be noted that other physical phenomena appear at the same time. This phenomenon is prominently exhibited in commercially available vacuum packaging of coffee beans. In other words, in the air, 1 grain, 1 grain of disjointed beans is put in a flexible bag of polyvinyl chloride, polyethylene, nylon resin, etc. and evacuated.
Instead of a piece of disjointed beans, it becomes an object with other physical properties, such as a hard baseball.

As described above, in the atmosphere, individuals having individual characteristics move with their own unique physical characteristics, but when placed in a flexible container and evacuated, the pressure difference inside and outside the container causes the individual The individual closely adheres and integrates,
It transforms into an object with completely different physical properties.

Utilizing the above basic theory, a soft and supple object (planar) in the atmosphere becomes hard like an iron plate in a vacuum. It can be considered to be used as a tool or tool.

[0007]

As a device similar to the one using the above-mentioned basic theory, there is a device for fixing the surroundings of the extremities of Japanese Patent Publication No. 50-50653. Certainly, the above-mentioned invention describes that small particles such as polystyrene beads are housed in a vacuum exhaust type cushion, and this is vacuum-sucked. However, in the device for fixing the limbs around, the vacuum exhaust type cushion is not used independently, but is used as a cushion between the shell and the limbs.

When the cushion structure is intended to be used as a self-supporting structure, the small particles are evacuated, so that a pressing feeling in the thickness direction surely gives a feeling like an iron plate. It has become a thing. However, there is little strength against the load in the bending direction, etc., because the shape is retained only by the tensile strength of the cushion material,
It was easy to lose independence.

The vacuum solid plate by the combination of the special shape net of the present invention is intended to solve the above-mentioned drawbacks of the conventional example.
It is possible to provide a vacuum solid plate with a combination of specially shaped nets that have sufficient strength not only against pressurization in the thickness direction but also against load in the bending direction, etc. It has become possible.

[0010]

That is, the vacuum solid plate formed by the combination of the specially shaped nets of the present invention stores a plurality of net-like objects facing each other so that the horizontal axis or the vertical axis meshes with each other in an outer bag. When the air in the outer bag is degassed, the horizontal axis or the vertical axis meshes with each other and solidifies.

Further, the vacuum solid plate according to the combination of the specially shaped nets according to the present invention accommodates a plurality of net-like objects which are opposed to each other so that the horizontal axis or the vertical axis meshes with each other in the outer bag via the plastic sheet. However, when the air in the outer bag is degassed, the horizontal axis or the vertical axis meshes with each other and solidifies.

Further, a plurality of net-like objects having a horizontal axis and a vertical axis are opposed to each other such that the horizontal axis or the vertical axis meshes with each other, or a pair of net-like objects having a horizontal axis and a vertical axis and a horizontal axis or a vertical axis. One of the features is that the net-like material having the horizontal axis or the vertical axis sandwiched between the two surfaces is opposed to each other so that the horizontal axis or the vertical axis meshes with each other.

In the above, the plastic sheet is also characterized in that it has a high hardness per unit area and is deformable as a whole, for example, a hard material having a large number of parallel or cross-shaped cuts formed therein. .

It is important for the structure of the net having the above-mentioned special shape to be a non-woven net in which the horizontal axis and the vertical axis forming the net intersect at a point. The original image of the net is that the horizontal axis and the vertical axis are woven like a wire mesh.
The feature of the non-woven net used in the present invention is often a resin net produced by injection molding or the like using a material such as a synthetic resin or a fiber reinforced resin (glass fiber, carbon fiber, etc.). That is, as shown in FIGS. 1 (a) and 1 (b), the cross-sectional shape has a horizontal axis and a vertical axis in two or three steps, and becomes wavy like a woven net, and the horizontal axis and the vertical axis intersect. There is nothing to do.

[0015]

Since the vacuum solid plate formed by combining the specially shaped nets of the present invention is constructed as described above, it is a sheet-like material that is hard per unit area and hard and deformable in a large area. It is possible to provide a very solid vacuum solid plate by the meshing of the special shape net.

Further, it has sufficient strength not only against pressure in the thickness direction but also against load in the bending direction,
Therefore, it has become possible to provide a vacuum solid plate that is a combination of specially shaped nets that are highly self-supporting.

Further, it is a useful vacuum solid plate which utilizes the property that a soft and supple object (planar shape) becomes hard like an iron plate when it is evacuated in the atmosphere, and is hardly deformed from its original shape in vacuum. Can now be provided.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vacuum solid plate formed by combining special shaped nets of the present invention will be described in detail below with reference to the drawings.

FIGS. 1 to 4 show the cross-sectional shape of each of the nets A and B used in the present invention, which is composed of a horizontal axis 1 and a vertical axis 2, and have a circular shape as shown in FIGS. 1 (a) and 1 (b). , Fig. 2
There are triangles such as (a) and (b), quadrangles such as FIGS. 3 (a) and (b), and semicircular shapes such as FIGS. 4 (a) and (b). It can be easily manufactured by the injection molding used.

That is, the net A in FIG. 5A has a two-stage structure in which the vertical axis 2 is attached to only one side of the horizontal axis 1, and the net B in FIG. Is attached to both sides (upper and lower) of the vertical axis 2 in a three-stage structure.
The horizontal axis 1 and the vertical axis 2 each have a round bar shape, but other cross-sectional shapes may be used.

6A to 6C are sectional views showing the assembling process. In this embodiment, a pair of nets A is shown on the horizontal axis 1.
Alternatively, the vertical axes 2 are made to face each other so as to mesh with each other (a), and the both sides thereof are sandwiched by the plastic sheets 3 and placed in the outer bag 4 (b), and then the inside of the outer bag 4 is deaerated. Then, the horizontal axis 1 or the vertical axis 2 of the pair of nets A meshes with each other to form a strong plate shape (C). Reference numeral 5 is a degassing nozzle attached to the outer bag 4.

It is important for the structure of the net having the above-mentioned special shape to be a non-woven net in which the horizontal axis 1 and the vertical axis 2 forming the net intersect at a point. The original image of the net is that the horizontal axis and the vertical axis are woven like a wire mesh. The features of the non-woven net used in this example are synthetic resin and fiber reinforced resin (glass fiber, carbon fiber, etc.).
It is often a resin net produced by injection molding or the like using a material such as. That is, the horizontal axis 1 and the vertical axis 2 have a two-step or three-step cross-sectional shape, and the horizontal axis 1 and the vertical axis 2 do not cross like a woven net.

In the above description, the plastic sheet 3 has a high hardness per unit area (1 cm ² ) and is a deformable material as a whole, for example, a hard material having a large number of parallel or cross-shaped cuts formed therein. Can be used.

Further, as the material of the outer bag 4, various materials commercially available for vacuum packing and the like, for example, polypropylene and nylon resins, other synthetic resins having excellent toughness, or laminates of these and cloths are used. And the like can be preferably used.

When the net A, the net B, the plastic sheet 3 and the like are simply put in the outer bag 4, they move separately and have little relation to each other. Therefore, the vacuum solid plate formed in a flat shape is very flexible at this stage and looks like a blanket or a carpet.

In the embodiment shown in FIGS. 7A to 7C,
A pair of nets A are made to face each other so that the horizontal axis 1 or the vertical axis 2 mesh with each other, and another net A is further laminated (a), and both sides thereof are sandwiched by the plastic sheet 3 and put in the outer bag 4. Above (b), when the inside of the outer bag 4 is deaerated, the horizontal axis 1 or the vertical axis 2 of the pair of nets A meshes with each other to form a strong plate shape (c).

In the embodiment shown in FIGS. 8A to 8C,
A pair of nets A are made to face each other so that the horizontal axis 1 or the vertical axis 2 are meshed with each other across the net B (a), and both sides are sandwiched by the plastic sheet 3 and placed in the outer bag 4 (b). ,
When the inside of the outer bag 4 is degassed, the horizontal axis 1 or the vertical axis 2 of the pair of nets A and B mesh with each other to form a strong plate-like shape (c).

FIG. 9 shows a perspective view of the embodiment shown in FIG. It shows a state in which a pair of nets A are combined, both sides of which are sandwiched by the plastic sheets 3 and further put in the outer bag 4. Reference numeral 6 denotes a large number of parallel or cross cuts formed in the plastic sheet 3. The cuts 6 give the plastic sheet 3 made of a hard material sufficient flexibility. Instead of the notch 6, a large number of small holes may be formed by punching or the like.

When the net A and the net B are merely contained in the outer bag 4, they are separately moved and have little relation to each other, and are themselves flexible. The plastic sheet 3 is also provided with flexibility by a large number of parallel or cross-shaped cuts 6. Therefore, the vacuum solid plate 11 formed in a flat shape is very flexible at this stage and looks like a blanket or a carpet.

After that, when the air inside the outer bag 4 was sucked by the vacuum pump through the degassing nozzle 5 provided in the outer bag 4 shown in FIG. The materials stick to each other. At this time,
The horizontal axis 1 or the vertical axis 2 of the net A or the net B is fitted between the horizontal axis 1 or the vertical axis 2 of the other side and is completely integrated.
Then, each unique physical property of each material is completely lost, and an object having one new physical property including the outer bag 4 is created. The vacuum solid plate 11 in this vacuum state is very hard, and is characterized by not being deformed like a veneer plate or an iron plate.

FIG. 11 shows an example of the planar shape of the vacuum solid plate 11. In the figure, (a) is T-shaped,
(B) is a shape obtained by diagonally cutting one corner of a rectangle, and (C) is a shape obtained by diagonally cutting a corner of an L-shape whose left and right are inverted,
