Description

[0001]
[Industrial application fields]
The present invention relates to a vacuum solid plate by a combination of special-shaped nets that can be used for various purposes because it is plastic in a normal state and can be quickly formed into a solid plate by applying a vacuum.
[0002]
[Prior art]
It is relatively new that appliances using vacuum are used in people's lives and customs.
[0003]
Among them, vacuum packs are the most popular and very useful packaging means. This vacuum pack plays a role of preventing oxidation and spoilage by blocking foods in the packaging container from the outside air by using a vacuum.
[0004]
By the way, it must be noted that other physical phenomena appear at the same time. This phenomenon is noticeable in commercially available coffee bean vacuum packs. In other words, in the atmosphere, one grain, one piece of beans is no longer one piece, one piece, when it is put in a flexible bag of polyvinyl chloride, polyethylene, nylon resin, etc. and evacuated. It becomes an object with different physical properties, like a hard baseball.
[0005]
In this way, individuals with individual characteristics in the atmosphere move with their own physical characteristics, but when placed in a flexible container and evacuated, the individual is completely separated due to the pressure difference inside and outside the container. It becomes an object with completely different physical characteristics.
[0006]
Using the above basic theory, using the physical properties of a soft and supple object (planar) in the atmosphere that hardens like an iron plate when evacuated, it is a tool or tool in human life and customs. It can be used as
[0007]
[Problems to be solved by the invention]
A device similar to the one using the above basic theory is a device for fixing the periphery of the limb described in Japanese Patent Publication No. 5-503653. Certainly, the above invention describes that small particles such as polystyrene beads are accommodated in an evacuated cushion and vacuum-sucked. However, in the device for fixing the periphery of the limb, the evacuation type cushion is not used independently, but is used as a cushion between the shell and the limb.
[0008]
When trying to use the cushion structure as a self-supporting structure, the space between the small particles is evacuated, so it will certainly feel like a steel plate against pressure in the thickness direction. ing. However, with respect to a load in the bending direction or the like, since the shape is held only by the tensile strength of the cushion material, the shape is not so strong and the self-supporting property is easily impaired.
[0009]
The vacuum solid plate by the combination of special shape nets of the present invention intends to eliminate the above-mentioned drawbacks of the conventional example, and not only against pressure in the thickness direction but also against load in the bending direction etc. It has become possible to provide a vacuum solid plate having a combination of specially shaped nets that have sufficient strength and are therefore self-supporting.
[0010]
[Means for Solving the Problems]
That is, the vacuum solid plate according to the combination of the special shape nets of the present invention accommodates a plurality of nets facing each other so that the horizontal axis or the vertical axis mesh with each other, and deaerates the air in the outer bag. In this case, the horizontal axis or the vertical axis meshes with each other and is solidified.
[0011]
The vacuum solid plate according to the combination of special shape nets of the present invention accommodates a plurality of nets facing each other so that the horizontal axis or the vertical axis meshes with each other in the outer bag via a plastic sheet. It is also characterized in that when the air in the outer bag is deaerated, the horizontal axis or the vertical axis meshes with each other and solidifies.
[0012]
Further, a plurality of nets having a horizontal axis and a vertical axis are opposed to each other so that the horizontal axis or the vertical axis mesh with each other, or a pair of nets having the horizontal axis and the vertical axis are arranged on both sides of the horizontal axis or the vertical axis. One of the characteristics is that the nets sandwiching the horizontal axis or the vertical axis face each other so that the horizontal axis or the vertical axis mesh with each other.
[0013]
In the above, the plastic sheet is also characterized in that it has a high hardness per unit area and as a whole is a deformable material, for example, a hard material formed with a large number of parallel or grid cuts.
[0014]
As the structure of the specially shaped net, it is important that the net is an unwoven net in which the horizontal axis and the vertical axis that form the net intersect at a point. As an image of an original net, it is common that the horizontal axis and the vertical axis are woven like a wire net. In many cases, the unwoven mesh used in the present invention is a resin mesh produced by injection molding or the like using a material such as synthetic resin or fiber reinforced resin (glass fiber, carbon fiber, etc.). That is, as shown in FIGS. 1 (a) and 1 (b), the cross-sectional shape has two or three horizontal axes and the vertical axis crosses the horizontal axis and the vertical axis as a woven net. Never do.
[0015]
[Action]
Since the vacuum solid plate according to the combination of the special shape net of the present invention is configured as described above, it is a sheet-like material that is hard per unit area, hard and deformable in a large area, and has a special shape when evacuated. A very solid vacuum solid plate can be provided by mesh engagement.
[0016]
In addition, there is provided a vacuum solid plate having a combination of specially shaped nets that have sufficient strength against not only pressure in the thickness direction but also load in the bending direction and the like. It became possible.
[0017]
Furthermore, it provides a useful vacuum solid plate that utilizes the property that a soft and supple object (planar shape) becomes hard like an iron plate when evacuated in the atmosphere, and hardly deforms from its original shape in a vacuum. I was able to do it.

【Example】
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a vacuum solid plate using a combination of special shape nets according to the present invention will be described in detail below with reference to the drawings.
[0019]
FIGS. 1 to 4 show the cross-sectional shapes of the respective axes consisting of the horizontal axis 1 and the vertical axis 2 of the meshes A and B used in the present invention, and are round shapes as shown in FIGS. There are triangles such as (A) and (B), quadrilaterals such as FIGS. 3 (A) and (B), and semicircles such as FIGS. 4 (A) and (B). It can be easily manufactured by the injection molding used.
[0020]
That is, the net A in FIG. 5 (a) has a two-stage structure in which the vertical axis 2 is attached to only one side with respect to the horizontal axis 1, and the net B in (b) has the horizontal axis 1 on the vertical axis. It has a three-stage structure attached to both sides (upper and lower) of the two. Each of the horizontal axis 1 or the vertical axis 2 has a round bar shape, but may have other cross-sectional shapes.
[0021]
6A to 6C are cross-sectional views showing the assembly process. In this embodiment, a pair of nets A are opposed so that the horizontal axis 1 or the vertical axis 2 meshes with each other (A), and both sides thereof are sandwiched between plastic sheets 3 and placed in an outer bag 4 (B). The inside of the bag 4 is deaerated. Then, the horizontal axis 1 or the vertical axis 2 of the pair of nets A mesh with each other to form a strong plate shape (C). Reference numeral 5 denotes a deaeration nozzle attached to the outer bag 4.
[0022]
As the structure of the specially shaped mesh, it is important that the mesh is a non-woven mesh in which the horizontal axis 1 and the vertical axis 2 forming the mesh intersect at a point. As an image of an original net, it is common that the horizontal axis and the vertical axis are woven like a wire net. The feature of the non-woven mesh used in this embodiment is often a resin mesh produced by injection molding or the like using a material such as synthetic resin or fiber reinforced resin (glass fiber, carbon fiber, etc.). That is, the horizontal axis 1 and the vertical axis 2 have two or three steps in cross section, and the horizontal axis 1 and the vertical axis 2 do not intersect with each other as a woven net.
[0023]
Further, in the above, the plastic sheet 3 has a high hardness per unit area (1 cm ² ), and as a whole, a deformable material, for example, a hard material in which a large number of parallel or grid cuts are formed is used. Can do.
[0024]
Further, as the material of the outer bag 4, various materials commercially available for vacuum packaging, for example, polypropylene and nylon resins, other synthetic resins having excellent toughness, or laminates of these with cloth, etc. are suitable. Can be used for
[0025]
The net A, the net B, the plastic sheet 3 and the like, when they are simply put in the outer bag 4, move separately and have little relevance. Therefore, the vacuum solid plate formed in a flat shape is very flexible at this stage and feels like a blanket or a carpet.
[0026]
7 (a) to 7 (c), a pair of nets A are opposed to each other so that the horizontal axis 1 or the vertical axis 2 meshes with each other, and another net A is further laminated (b). After both sides are sandwiched between plastic sheets 3 and placed in the outer bag 4 (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 mesh with each other to form a strong plate shape. (C).
[0027]
8 (a) to 8 (c), a pair of nets A are opposed so that the horizontal axis 1 or the vertical axis 2 mesh with each other across the net B (A), and both sides are plastic. When the inside of the outer bag 4 is deaerated after being sandwiched between the sheets 3 (b) and the inside of the outer bag 4 is deaerated, the horizontal axis 1 or the vertical axis 2 of the pair of nets A and B meshes with each other to form a strong plate ( C).
[0028]
FIG. 9 shows a perspective view of the embodiment shown in FIG. A state is shown in which a pair of nets A are combined, and both sides thereof are sandwiched between plastic sheets 3 and further put into an outer bag 4. Reference numeral 6 denotes a large number of parallel or grid-like cuts formed in the plastic sheet 3. The notch 6 gives the plastic sheet 3 made of a hard material sufficient flexibility. In place of the notch 6, a large number of small holes may be formed by punching or the like.
[0029]
The nets A and B simply move separately when placed in the outer bag 4 and have little relevance and are themselves flexible. The plastic sheet 3 is also given flexibility by a large number of parallel or grid-like cuts 6. Therefore, the vacuum solid plate 11 formed in a flat shape is very flexible at this stage and feels like a blanket or a carpet.
[0030]
Thereafter, when the air inside the outer bag 4 is sucked by a vacuum pump through the deaeration nozzle 5 provided in the outer bag 4 shown in FIG. 10, the inside becomes a vacuum state over time, and the incorporated materials are mutually connected. In close contact. At this time, the horizontal axis 1 or the vertical axis 2 of the net A or the net B fits between the horizontal axis 1 or the vertical axis 2 on the other side and is completely integrated. And each original physical property of each material is completely lost, and an object having one new physical property including the outer bag 4 is born. The vacuum solid plate 11 in a vacuum state is very hard and is characterized by being not deformed like a veneer plate or an iron plate.
[0031]
FIG. 11 shows an example of the planar shape of the vacuum solid plate 11. In the figure, (A) is a T-shape, (B) is a shape obtained by obliquely cutting one corner of a rectangle, (C) is a shape obtained by obliquely cutting one corner of an L-shape that is reversed left and right, and (D) is a U-shape. , (E) show a state of being formed in steps. Reference numeral 12 denotes a deaeration port.
[0032]
12 to 14 show examples of the three-dimensional shape of the vacuum solid plate 11. In FIG. 12, (a) is a cylinder with an elliptical section, (b) is a cone with an elliptical section, (c) is a cylinder with a triangular section, (d) is a cylinder with a square section, and (e) Indicates an arch shape with a semicircular cross section, (f) indicates a wave shape, (G) indicates an elbow shape, and (H) indicates a bowl shape.
