Description

  The present invention belongs to the technical field of aquarium fish tanks, and in particular, uses a tank or a container in combination with a separate transparent observatory tower-type auxiliary container so as to be continuous with the water contained in the tank. It relates to a set of water tanks that realizes a water column that protrudes upward from the water surface, allows ornamental fish to freely move into and out of the water column, or inserts water plants and allows them to be observed from the side. is there.

  Combining a general container with an open upper part and a container with an upper part closed and a lower part open on the contrary, using the atmospheric pressure, two levels of continuous water or water with a difference in height are realized, In the past, more than a dozen applications have been filed for the idea of allowing ornamental fish to move between the two containers, including the public information 56-10367. (Public information: 56-10367, 56-75869, 56-75870, 56-96970, 56-134170, 58-178867, 59-64658, 60-28861, 62-24659, 62-24659, Hei7 −7414, practical use registration 3092772, and design registration 587547, 587549, 1171155, and 1171156).

  In the embodiments described in the background art, it was necessary to provide an air vent plug on the top, or it was too large for easy use in ordinary households. The practical registration 3096722 pays attention to the simplicity of use at home, but requires a pump and a kitchen wrap to fill the upper container with water, and the simplicity is still insufficient. In general, the conventional technology has a problem in that it does not have sufficient simplicity and convenience that can be used very easily in ordinary households.

  The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a pump that can be easily used in general households, that is, a pump and a kitchen wrap. Without using any assistance such as filling the upper observation tower type auxiliary container with water with almost one touch, it is possible to observe ornamental fish and aquatic plants from the side direction, and it is compactly combined when not in use. The purpose of the present invention is to provide a set of water tanks with a built-in auxiliary water tank so that the storage space is not troublesome.

  The difficulty in filling the upper container with water can be solved by determining and combining the shapes, dimensions, and positions of the two containers and the holder under certain relational conditions, as described in claim 1. The user fills the upper container inside the lower container and pours water into the lower container. Then, the user only needs to lift the lying upper container vertically to complete the filling of water. After the filling, the upper container may be fixed by the holder, and a gap through which the ornamental fish and the like can enter and leave may be secured in the water.

  The retainer must secure the upper container within a range that does not allow air to enter the upper container, while maintaining a certain gap between the upper container and the bottom surface of the lower container. Very simple things are enough. By using gravity, the upper container can be leaned against the edge of the lower container at an angle, and the gap created between the opening of the upper container and the bottom of the lower container can be used as a passage for ornamental fish as it is. In this case, a small projection-shaped holder for preventing the upper container from slipping down sufficiently satisfies the purpose.

Since the present invention is configured as described above, it has the following effects.
A complete water tank comprising upper and lower containers and a holder as shown in claim 1 is a water column that can observe an ornamental fish or aquatic plant from the side in the upper container and protrudes above the water surface while being continuous with the water in the lower container. Not only can it be realized simply, but at that time, it is easy to fill with water in the upper container, so that anyone can realize this with almost one touch without any need for pumps and other tools. In addition, there is the simplicity that cleaning and the like of a container which is frequently required at the time of actual use is much easier than in the past.

  In addition, this aquarium has the convenience of being able to enjoy the vertical movement of ornamental fish and the growing condition of vertically long aquatic plants even in very limited places such as the corner of the table, and the upper container inside the lower container when not in use. Can be completely stored, and has the convenience of not taking up space, and can be widely used in ordinary households.

  The holder according to claim 2 has a very simple structure and enables the above-described set of built-in water tanks to be realized in a wide variety of forms.

An embodiment of the invention will be described with reference to the drawings.
1 to 9, the upper container A is formed by means such as extrusion molding of a transparent material such as glass or plastic. The lower container B may be an opaque material such as pottery and porcelain. The projecting, hook-shaped or trapezoidal holding tool C is integrally formed of the same material as the lower container B and the upper container A as shown by C1 and C3 in FIGS. 2 and 6, or in FIGS. Like C2 and C3, they are separately formed of a metal or other material so as to be attached to or detachable from the lower container. In the case of a fixed type, an adhesive may be used. Also, a step may be provided on the bottom surface of the lower container B itself, and this step may be used as it is as a holder. As shown in C5 of FIG. 7, a method of fitting the upper and lower containers and making the upper container movable as shown by the upper container position 13 and the tip end radius 14 at the beginning is also possible.

  The upper container A is sized so that it can be easily caused by a person holding the closed end even when it is filled with water, and has sufficient strength to retain strength with a heavy and fragile material such as glass. Secure wall thickness. When the upper container A is tilted sideways so that the opening 4 faces the side, the entire upper container A fits in the lower container B, and when water is poured from above, air remains inside the upper container A. 2. The stand according to claim 1, wherein, when standing, on the other hand, when the stand is set up, it is protruded from the water surface in the lower container B so that the inside of the lower container B is maintained at such a large height that the ornamental fish and the like can be sufficiently observed from the side direction. The shapes and dimensions of both containers are adjusted according to the relevant conditions (A) to (C).

  Within the range of this condition, the type, material and shape of the holder can be various as shown above. However, in order to ensure stability, attention should be paid to each shape depending on the shape. In the small projection-like holding tool C1 in FIG. 3, the holding tool holding position 8, the center of gravity 11 of the upper container, and the edge holding position 9 so that the upper container A is not fallen down and is stable when the upper container A is held against the edge of the lower container B. Are determined while paying attention to the arrangement of the items in the order described above. The S-shaped hook-shaped holder C2 in FIG. 4 in which a fulcrum is formed at the lower part of the upper container A, and the rotating shaft fixed type holder C5 in FIG. Keep in mind.

  In the hook-shaped holder C4 in FIG. 6, the size and shape of the play between the hook and the like are adjusted according to the thickness of the edge so that the hook does not rattle and fall down when the hook is installed on the edge. In addition, in the trapezoidal holder C3 in FIG. 5, one to several small tables are used, but a non-slip material is used so that the upper container A is stable without shaking when placed thereon. It is adjusted by, for example, providing a groove for fixing the edge of the container A.

The related conditions described in claim 1 will be specifically described below. FIG. 1 shows an example in which a substantially columnar transparent upper container A and a substantially rectangular parallelepiped lower container B are combined, and the upper container A is stood upright on the edge 7 of the lower container B by a small projection-shaped holder C. Is shown. FIG. 3 is a sectional view thereof. In this case, as described in claim 1,
(A) As shown in FIG. 2, the upper container A fits completely in the lower container B, and has a shape and dimensions that allow the air in the upper container A to escape when water is poured.
(A) On the other hand, as shown in FIG. 3, the upper container A in the upright state keeps the water column height e enough to allow viewing from the side and allows the ornamental fish to enter and exit. At the same time that the gap height f is secured,
(C) On the other hand, the water surface 2 in the state of FIG. 3 should not be so low as to initially drop below the water surface 12 when water is poured in the state of FIG.
The size and positional relationship between the upper and lower containers and the holder C1 are adjusted.

In order to see the above relationship more specifically, numerical values are calculated in a simple case where both the upper and lower containers are rectangular parallelepipeds. In FIG. 5, in order to satisfy the relational condition (A), the upper container A is a rectangular parallelepiped with an inner method of 10 cm × 10 cm × 20 cm, and the lower container B is a rectangular parallelepiped with an inner method of 9 cm × 9 cm × 17 cm. It is assumed that the upper container is standing in the vertical direction by the holder C3. In this case, looking at (a) and (c), the height of the holder C3, and hence the size of the gap height f, is now determined by the error caused by the thickness of the material of the upper container, the ornamental fish, the volume of the holder, and the like. If you ignore, a simple calculation:
{(10 × 20) − (9 × 9)} d + (9 × 9) × (17 + f) = 2000
f <d (unit is cm: the same applies hereinafter)
As is evident from the above, even if the lower container was initially filled with water to just below the rim, as long as the trouble of adding water was avoided,
Water surface height d = gap height f = 3.12 (rounded to two decimal places: the same applies hereinafter)
Cannot be larger than From this, if the size of the gap height f is required to be 2 cm or more for entering and exiting ornamental fish, etc., in this example,
2 <f <3.12
Is derived. Therefore, the height of the holder C3 must also be determined within this range. Under the same conditions, the water column height e also becomes minimum when the gap height f is 2 cm and the water surface height d is 3.87 cm, and becomes maximum when both f and d are 3.12 cm.
15.13 <e <17
It can be calculated that

  Also, as shown in the condition (a), the upper container A, which is placed sideways in the lower container B when water is poured, must have a dimension within a range that can be raised by holding the tip thereof. In the example shown in FIG. 5, this is possible because the maximum length on the cross-sectional view of the upper container A is 19.24 cm of the diagonal length, which is 20 cm or less in the inner width of the lower container B. it is obvious.

  The shapes of the upper container A and the lower container B may be various as long as the above-mentioned relational conditions are satisfied. FIG. 8 shows an example in which a substantially gourd-shaped lower container B is provided with a substantially prismatic and arched pipe-shaped upper container A. Although the holder C is illustrated as a small projection type, another method may be used in combination. FIG. 9 is a plan view showing a state in which two upper containers A are accommodated in a lower container B in the example of FIG.

It is a perspective view of the combination of an upper container and a lower container at the time of actual use. It is sectional drawing at the time of storing an upper container in a lower container and pouring water. It is sectional drawing of the state which stood the upper container after pouring water. It is sectional drawing at the time of fixing an upper container with the S-shaped hook-shaped holding | maintenance tool. It is sectional drawing at the time of installing an upper container using a trapezoid holder. It is sectional drawing at the time of fixing an upper container with a hook-shaped holding tool. It is sectional drawing at the time of fixing an upper container with the holder of a rotating shaft fixed type. It is a perspective view of what combined the gourd type lower container and two deformation | transformation upper containers as an application example. FIG. 9 is a plan view when the upper container is housed in the lower container in the example of FIG. 8.
