DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium fish tank, and more particularly to an improvement of an aquarium fish tank in which a front glass and left and right side glass are integrally formed by a seamless bent glass. .

[0002]

2. Description of the Related Art Heretofore, as a glass plate constituting an aquarium for aquarium fish, a bent glass formed by bending a single rectangular glass plate integrally into a U-shape in a heating furnace has been used.
There is no joint pillar at the corner between the front glass and the glass on both left and right sides, and a curved glass surface with good transparency is provided, so that the aquarium fish tank with bent glass has improved viewing function from the front and both left and right directions Is already widely known.

The aquarium for aquarium fish is not limited to the aquarium for aquarium fish using the bent glass described above, and the temperature in the aquarium is not limited to a general aquarium which has been known for a long time using a joint pillar at a corner portion. Water may form on the glass surface of the aquarium due to the difference between the temperature of the aquarium and the temperature outside the aquarium. The placed peripheral parts may get wet with water. Conventionally, as a countermeasure against such a problem, Japanese Utility Model Publication No. Sho 56-41500 discloses an aquarium fish tank provided with a drainage groove on an outer peripheral portion of a bottom frame of the water tank for receiving water drops flowing down along the glass surface. ing.

[0004]

Among the aquarium fish tanks, in the aquarium fish tank in which the front glass and the left and right side glass are integrally formed by bending glass, the front glass and the left and right side glass are formed at corner portions. Since it is formed continuously and seamlessly, it lacks flexibility as a whole, and if an unreasonable pressure or impact acts on a part of the glass, the entire load will concentrate on this distorted part. However, there is a problem that it easily leads to destruction.

For example, in the case where the bent front glass and the lower end surfaces of the left and right side glass are placed on an installation table composed of a complete horizontal plane, the entire length of the front and left and right glass lower end surfaces becomes uniform. Because of the contact on the mounting table, the glass does not in part be subjected to particularly unreasonable pressures.
However, if the bent front glass and the lower end surfaces of the left and right side glass are placed on an installation table with an incomplete flat surface that is slightly inclined, the entire length of the front and left and right glass lower end surfaces will be uniform. An unstable state is created in which a gap is created between a part of the glass and the surface of the installation table without touching the top, and if an impact is applied from the outside in this state, the glass part with this gap will become another glass part The intensive load acts to break the glass.

[0006] The appreciation fish tank using the bent glass, since the corner portion is formed by a glass curved surface with good transparency, the demand for the appreciation function from the front and both right and left sides, the demand will continue in the future. Although there is a tendency to increase, due to the above-mentioned problems, as a tank maker, when the user manages the tank, even if there is some problematic handling, the tank is not easily destroyed Such a structure is required.

[0007] The user of the bent glass aquarium should pay particular attention to the management of the aquarium, because moss is generated inside the aquarium due to accumulation of leftover food and excrement of fish.
This is the handling of the water tank when cleaning to remove moss attached to the water tank.

[0008] In general, when cleaning a water tank, many users leave a small amount of water without draining all the water in the tank, and leave bottom gravel for planting aquatic plants in the tank. Carry it to the washing place while keeping it in the water tank A as shown in FIG.
Is tilted while supporting the corner E of the bottom frame D in which the corner C of the bent glass B is fitted on the washing scene F as a fulcrum, and drains the water inside.

As described above, when the corner C of the bent glass B of the water tank A is brought into direct contact with the washing scene F via the corner E of the bottom frame D, the bent glass B causes the load of the entire water tank A in which water remains. Therefore, an improper pressure is concentrated on the corner portion C of the bent glass B, and the bent glass is broken from this portion even if a slight impact is applied at the time of the contact.

[0010] On the other hand, Japanese Utility Model Publication No.
The appreciation fish tank of No. 6-41500 is provided with a drainage groove on the outer peripheral portion of the bottom frame of the tank to catch water drops hanging down along the glass surface, but since this tank is not made of bent glass, As described above, when cleaning the water tank, even if the water tank is tilted with the corner as a fulcrum, there is no problem that the glass is broken.

[0011]
