Abstract

PROBLEM TO BE SOLVED: To enable to easily and safely observe underwater by filling the inside of a main body formed with an observation plane and a cover, bringing up the water to make the observation plane above the water surface and equipping a float on the main body. SOLUTION: Fundamental constitution elements are an observation plane 1, surrounding cover 3, and floats 2 as shown in the diagram. Since the part surrounded by the observation plane and the cover 3 is tightly closed, water can be brought up from the water surface to make the observation plane above the water surface. Floating force to bring up water high than the water surface is obtained by the floats 2. Though the float 2 is positioned deviated to the left side in the diagram, it is because to compensate the volume of water to be brought up is larger in the left side. Thereby the observation plane 1 can be inclined to a desired inclination. In that case, the shape and the attaching position are not limited only if the observation is floated up and inclined at a desired inclination.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Observing underwater with underwater glasses is difficult and dangerous for people who are not good at swimming and for small children. The present invention relates to a tool that allows such people to easily and safely observe the sea.

[0002]

2. Description of the Related Art Since there are waves on the sea surface, it is difficult to see inside the sea without using anything.
A transparent plate, such as glass, is sandwiched between water and air to flatten the boundary surface so that you can clearly see inside the sea. The most common means is underwater glasses. Underwater glasses, as shown in Figure 8, observer's eyes (8)
Is sealed with a rubber cover (9) and a glass plate to create an air space (6) around the eyes and push it into the water (5). The glass plate separates water (5) and air (6),
The interface between the two is flattened to form the observation surface (1). Inevitably, in order to look into the sea, you need to wear underwater glasses and immerse your face in the water.

A tub-shaped tool shown in FIG. 10 also exists as a conventional technique, and is used when a fisherman picks a shell. FIG. 9 is a sectional view thereof. Also in this case, the observation surface (1) is made of a glass plate or the like, and the air (6) is pushed into the water (5) to flatten the boundary surface between them. With this tool, you do not need to immerse your face in water.

[0004]

The method of looking in water using underwater glasses is based on the premise that a swim can be performed as such. Even if you can swim a little, it is dangerous to let a small child use underwater glasses.

On the other hand, the tub-shaped tool has a drawback that when water enters from above with water, the water accumulates inside and becomes difficult to see. Therefore, the partition is made as high as possible, but this makes the angle at which you can look into the sea narrow and limited, and the body becomes large and it is inconvenient to carry it easily. I have. Rather than being used casually by the general public, it can be said that it is positioned as a dedicated tool for fishing.

[0006] Underwater glasses and trough-shaped tools also push the air into the water to create an interface between the water and the air. That is, in both FIG. 8 and FIG. 10, the observation surface (1) is the water surface (4).
Is lower than Such a condition causes a need to immerse the face in water in the case of underwater glasses, and in the case of a tub-shaped tool, causes a problem that water enters from above and accumulates in the inside.

[0007]

As shown in FIG. 3, the inside of a main body formed by an observation surface (1) and a cover (3) made of a transparent plate is filled with water (5). Lift the water (5) above the water surface (4). By doing so, the observation surface (1) is formed above the water surface. In order to obtain buoyancy for lifting the water (5), a buoy (2) is provided on the main body as shown in FIG.

[0008]

[Function] Since the observation surface (1) is above the water surface (4),
Underwater viewers do not have to immerse their faces in water. If the observation surface (1) is formed obliquely, there is no need to look directly from above, and observation is facilitated.

On the other hand, the tub-shaped tool has a problem that it becomes difficult to see if water enters, but in the present invention, the observation surface (1) is above the water surface (4), and By making the oblique angle, even if water is applied by waves, the observation surface (1) does not accumulate water and the observation in the water can be continued comfortably.

[0010]

Embodiment 1 As shown in FIG. 1, an observation surface (1), a surrounding cover (3) and a float (2) are basic components of the present invention. FIG. 2 shows a state at the time of actual use. As shown in FIG. 3 which is a cross-sectional view of FIG. 2, the portion surrounded by the observation surface (1) and the cover (3) is sealed, so that the water (5) is higher than the water surface (4). Lifting, the observation surface (1) can be made above the water surface (4). In the present invention, the buoyancy (2) provides the buoyancy for lifting the water (5) above the water surface. In FIG. 1, the float (2) is arranged to be deviated leftward in the figure, because the volume of water to be lifted is larger on the left side, and is offset. Thereby, the observation surface (1) can be maintained at a desired inclination. In the present invention, the shape of the float and the mounting position are not limited to this embodiment as long as the objective of floating the observation surface and obtaining a desired inclination is achieved.

[0011]

Embodiment 2 FIG. 4 shows an example in which two observation surfaces are provided. It is the same as Example 1 except that there are two observation surfaces. By using the second embodiment, a plurality of persons can observe the water from different directions. In addition, since the shape has symmetry, it has a feature that mounting of the float is easy.

[0012]

Embodiment 3 FIG. 7 shows an embodiment in which the observation surface (1) is spherical. Since the observation surface (1) is spherical, the shape of the cover (3) and the shape of the float (2) are changed, such as a cylindrical shape as shown in FIG. 7, but the basic configuration and principle are implemented. Same as Example 1. When the third embodiment is used, the underwater looks distorted, and is more interesting than the case where the observation surface is flat.
In this embodiment, an example in which the observation surface is a spherical surface has been described. However, in the present invention, the shape of the observation surface is not limited. Depending on the shape,
The observation surface (1) can also be made so as to double as the cover (3).

[0013]

Embodiment 4 FIG. 5 shows an example of a float that can be removed. A key-shaped mounting means (7) is mounted on the float (2). FIG. 6 is a sectional view showing a state in which the float of FIG. 5 is attached. By fitting the cover (3) into the gap between the mounting means (7) and the float (2), the float (2) is attached to the main body (the portion formed by the observation surface (1) and the cover (3)). Float (2) and mounting means (7) by the buoyancy of the float and the force of sinking the body containing water inside
Is pressed against the cover (3), so that it does not come off during use even if it is simply fitted.

[0014]

According to the present invention, the observation surface (1) for observing the inside of the sea is above the water surface (4), and the internal water (5) is used for water surface (4).
A lift (2) for lifting up is provided. The observation surface (1) has a shape in which water does not accumulate thereon, such as an inclined plane or curved surface (see FIGS. 1 and 3). With the above-described device, means for easily and safely observing the water is provided.
