Description

  The present invention relates to an aquarium for breeding ornamental fish, and more particularly to an improvement in a large aquarium fish tank having a rectangular parallelepiped shape and a length in the long side direction of 90 cm or more.

Aquarium fish tanks are most commonly square or rectangular cubes. Among such rectangular cubic aquariums, particularly in the case of a tank with a long side direction, that is, a lateral length of 90 cm or more, called a large tank, the tank itself withstands the internal water pressure and causes harmful deformation. In order to prevent this from happening, as seen in Patent Documents 1 and 2, an intermediate reinforcing rod is often attached to the central portion of the upper frame.
Design Registration No. 547621 That is, as shown in FIG. 6, the longitudinal direction of the frame-like upper frame (102) made of synthetic resin attached along the upper edge of the peripheral side wall (101) made of transparent glass having four surrounding surfaces as shown in FIG. In many cases, an intermediate reinforcing rod (103) is attached in a horizontal shape at the center of the frame.

  The intermediate reinforcing rod (103) is generally made of a synthetic resin extruded mold having a U-shaped cross-section, and the upper surfaces of both end portions are inwardly convex edges (102a) for supporting the glass lid of the upper frame (102). Attached to the lower surface of the steel plate by direct bonding or separately by using a separate mounting piece. Therefore, as shown in FIG. 7, the inner convex edge is formed between the upper surface of the glass cover supporting inner convex edge (102a) of the upper frame (102) and the upper surface of the intermediate reinforcing rod (103). A step (h) corresponding to the thickness of (102a) is generated.

  Due to such a step, the glass lid (104) that closes the upper surface opening of the aquarium (100) has a large 1 corresponding to the frame-shaped upper frame (102), regardless of the presence of the intermediate reinforcing rod (103). One glass plate must be used. As for the said glass cover (104), the lower surface of a periphery is bear-supported on the inward convex edge (102a) for glass cover support of an upper frame (102).

  However, since the glass lid (104) itself is a single sheet having a large area, when transporting the water tank, it must be transported in a fully protected packaging state so as not to break during handling. It was extremely troublesome. In addition, it is necessary to use a relatively thick glass plate to guarantee strength, which is not only costly, but also heavy and inconvenient to handle. The problem was that it was difficult to work.

  To solve this problem, the intermediate reinforcing rod (103) is integrally formed at the same height level as the upper frame (102), and this is provided with a glass lid support function so that the glass lid (104) is moved to the left and right. Of course, it can be considered that it is divided into two.

  However, when the entire upper frame is integrally molded with a synthetic resin, a mold corresponding to the size of the water tank must be prepared and molded separately. For this reason, it is disadvantageous not only in manufacturing cost but also in storage and transportation in the handling process until it is attached to the bulky water tank itself.

  For this reason, the upper frame (102) can be adapted to water tanks of various sizes by forming each side with an extrusion mold material by extrusion molding of synthetic resin, cutting it to the required dimensions and connecting it at the corners. It is common to make it.

  However, in this case, since the intermediate reinforcing bar (103) needs to be joined to the upper frame (102) on the lower surface side of the upper frame (102) as described above, the intermediate reinforcing bar (103) The upper surface is positioned at a position one step lower than the frame (102), and a step (h) is generated between them, thereby causing the above-described problems.

  In view of the above-mentioned problems of the conventional large tank, the present invention provides an improvement proposal that can make the glass lid of the large tank with a divided configuration advantageous for handling by the simplest structural modification. With the goal.

The present invention provides the following means for solving the above problems.
[1] An upper frame made of a synthetic resin extruded mold having a frame shape attached along the upper edge of the peripheral side wall of the four peripheral surfaces. The upper frame has an upper frame on the lower surface of the inner convex edge for supporting the glass lid. In a large aquarium for ornamental fish, in which an intermediate reinforcing rod is attached horizontally in the longitudinal center of the frame,
A glass lid receiving frame is attached along the length direction on the intermediate reinforcing rod,
The glass lid receiving frame is disposed to overlap the upper surface of the intermediate reinforcing rod, and has a step-eliminating strip plate portion having a thickness corresponding to the thickness of the inward convex edge for the lid plate support of the upper frame, and the strip plate A large aquarium for ornamental fish, characterized in that it has a partitioning ridge portion that is located at the center in the width direction of the portion and protrudes upward.
[2] The glass lid receiving frame is formed in a substantially U-shaped cross-section having a downward convex edge hanging downward on both side edges of the step-resolving strip corresponding to the width of the intermediate reinforcing collar, and the intermediate reinforcing collar The large aquarium for ornamental fish according to [1] above, which is fitted and fixed to the upper surface from the upper surface side.

  According to this invention, as described in the above item [1], the glass lid receiving frame is attached along the length direction on the intermediate reinforcing rod. Accordingly, the intermediate reinforcing rod is further reinforced by the glass lid receiving frame, and the strength of the large tank can be further enhanced, and the glass receiving frame has a step-resolving strip and a partitioning ridge. Thus, glass lid bearing surfaces having the same plane as the upper surface of the inner convex edge for glass lid bearing of the upper frame can be formed on the left and right sides of the glass lid receiving frame. Therefore, it is possible to divide the glass lid into left and right parts, and to stably support the lower surface of the peripheral edge of the four sides around each divided lid piece. Although this is a glass cover of a large aquarium, it can be used for transportation, storage, etc. in a state of being divided into two parts, and the divided lid pieces can be stacked and stored in the aquarium body to be transported and stored. This is possible and advantageous in handling. In addition, since it is sufficient for each divided lid piece to have strength corresponding to the area, it is possible to apply a thin plate glass as compared with the case where the entire glass lid is composed of a single plate glass, and the cost can be reduced. Reduction and weight reduction can be achieved, which is advantageous in handling, and can be easily opened and closed on the upper surface of the water tank. Moreover, the mutual interference | interference of a division | segmentation lid piece can be prevented by presence of the convex strip part for division.

  Further, according to the configuration described in the above item [2], the glass lid receiving frame is formed in a U-shaped cross section downward, so that it can be easily assembled to the intermediate reinforcing rod of the water tank under the correct positioning state. In addition, the position in the assembled state can be reliably maintained.

  Next, preferred embodiments of the present invention will be described with reference to the drawings.
