Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aquarium that is used for keeping fish for appreciation and live fish for serving food at home or in various stores.

[0002]

[Prior Art]

 It is generally desired that this type of water tank be made of a transparent material so that the inside of the water tank can be easily seen from the outside, but the conventional water tank is generally made of synthetic resin such as acrylic resin. , Which consisted entirely of glass, and could be broadly divided into two types.

[0003]

[Problems to be solved by the device]

 However, in the case of the former synthetic resin, not only the transparency is poor, but also scratches such as scratches are likely to occur on the surface of the aquarium, and the scratch marks are very noticeable in appearance, so that the appearance is aesthetic. As a required aquarium for viewing, there are fatal drawbacks. On the other hand, in the latter case where the whole water tank is made of glass, it has excellent aesthetics and does not have the drawbacks of synthetic resin, but it has the drawback that it is not easy to perforate the bottom of the water tank. .. That is, in a large water tank, it may be necessary to form a drain hole at the bottom of the water tank or to form a hole for connecting a pipe for supplying water or air into the water tank. In a water tank, cracks were likely to occur during the drilling of such drainage holes, making it very difficult. In addition, the glass aquarium has the disadvantages that its material cost and processing cost are considerably higher than those made of a synthetic resin, which makes it expensive, and also has a mechanical strength. In the case where a water tank is made of a relatively thin glass, there is a problem that a reinforcing frame must be additionally attached to the corner portion of the water tank bottom where high water pressure acts.

The present invention has been proposed in view of the above points, and it is possible to easily perform processing such as perforation on the bottom of the aquarium, and to make the aquarium surface scratches and the like less likely to be aesthetically pleasing. Moreover, it is an object of the invention to provide a water tank which is excellent in strength and can be manufactured at low cost.

[0005]

[Means for Solving the Problems]

 A water tank according to the present invention as claimed in claim 1, which is proposed to achieve the above object, has a glass outer peripheral side wall part and a synthetic resin bottom plate part, and the glass outer peripheral side wall part. Has a structure in which the bottom side thereof is joined to the synthetic resin bottom plate so as to be closed by the synthetic resin bottom plate.

Further, in the water tank according to the present invention as set forth in claim 2, in the structure according to claim 1, the lower end portion of the outer peripheral side wall portion is fitted on the upper surface side of the synthetic resin bottom plate portion. A concave portion is formed, and the concave portion is filled with a waterproof seal between both the lower end portion of the outer peripheral side wall portion and the bottom plate portion and a caulking material for bonding.

[0007]

[Action]

 In the water tank according to the present invention according to claim 1 having the above-mentioned structure, since the outer peripheral wall portion is made of glass, it is difficult to have flaws and is excellent in aesthetic appearance, and the bottom plate portion of the water tank is made of synthetic resin. Therefore, the total material cost and processing cost can be reduced as compared with the case where the whole is made of glass. Since the bottom plate is located at the bottom of the water tank, which is difficult to see in appearance, even if the bottom plate is damaged, the aesthetics of the whole water tank will not be greatly impaired. The aesthetic value of is not significantly reduced. Further, if the bottom plate of the water tank is made of synthetic resin, various perforating work etc. can be easily performed on the bottom plate, and it is possible to avoid accidentally cracking the bottom plate due to the perforating work. It Further, by increasing the thickness of the bottom plate portion on which the highest water pressure acts, the strength of the water tank can be easily improved.

In the water tank according to the present invention as set forth in claim 2, since the lower end of the outer peripheral side wall portion is fitted into the concave portion of the bottom plate portion and the concave portion is filled with the caulking material, the caulking material is It can be efficiently filled so as to effectively act on the adhesion of, and a sufficient waterproof seal and adhesion between both the outer peripheral side wall part and the bottom plate part can be achieved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an example of a water tank according to the present invention, FIG. 2 is a sectional view of an essential part showing an example of a joined state of the bottom of the water tank, and FIG. 3 is a sectional view taken along line XX of FIG. In this water tank, a box-shaped water tank body A having an opening 3 formed on the upper surface is formed by both the outer peripheral side wall portion 1 made of glass and the bottom plate portion 2 made of synthetic resin. A decorative plate 4 is provided on the outer periphery of the lower part of the. Here, in the outer peripheral side wall 1 made of glass, four transparent plate glasses 1a to 1d are arranged in a plane rectangular shape as shown in FIG. 3, and the end parts of the plate glasses 1a to 1d which are in contact with each other are bonded. The caulking material C having a property is adhered to each other. As such a caulking material, for example, "TOray Dow Corning Silicone Co., Ltd. trademark SE792 sealant, Primer D" is applied, and such caulking material is preferable because of its excellent adhesiveness and sealing property to the glass surface.

The bottom plate 2 is composed of a plate member made of a relatively thick synthetic resin such as acrylic resin, and has an upper peripheral edge made of glass as shown in FIG. A recess 2a for inserting the lower end of the outer peripheral wall 1 is formed in series. The outer peripheral side wall portion 1 made of glass is placed in a positioned state on the bottom plate portion 2 by being fitted into the concave portion 2a, and the bottom portion is closed. Further, the recess 2a is filled with caulking material Ca, and the caulking material Ca provides a water-tight seal between the bottom plate portion 2 and the outer peripheral side wall portion 1 and firmly adheres them together. Incidentally, a caulking material Cb is further applied to the corner where the upper surface side of the bottom plate portion 2 and the lower portion of the outer peripheral side wall portion 1 are joined as the second caulking process. As the caulking materials Ca and Cb, the same caulking materials C as described above are applied, as they are excellent in adhesive strength to the surface of glass or synthetic resin and waterproof sealing property.

In FIG. 1, reference numeral 5 is a hole for drainage or water supply provided at an appropriate position of the bottom plate 2 made of synthetic resin. Since the decorative plate 4 is made of a synthetic resin such as acrylic resin similar to the bottom plate 2, it is provided below the aquarium body A so that it can function as a pedestal for the aquarium body A. Further, the height is taken into consideration so as to blind the joint between the bottom plate portion 2 and the outer peripheral side wall portion 1. The decorative plate 4 is appropriately provided with an opening / closing door 4a and the like for performing maintenance of a drainage pipe and the like connected to the bottom of the water tank body A.

In the water tank having the above-mentioned structure, since the outer peripheral side wall portion 1 of the water tank body portion A is made of glass, it is possible to make the water tank excellent in transparency, scars less likely to occur, and excellent in aesthetics. On the other hand, since the bottom plate portion 2 in which the hole 5 for drainage is formed is made of synthetic resin, it is easy to pierce the bottom plate portion 2 so that the formation of the hole 5 can easily cause cracks or distortions in the bottom plate portion 2. There is no such thing. In addition, when water is stored in the water tank, a considerable amount of water pressure acts on the bottom of the water tank main body A, but the outer peripheral side wall 1 and the bottom plate 2 are joined together with good adhesiveness and water-proof sealing. Since the excellent caulking materials Ca and Cb are caulked and applied in two steps, no water leakage will occur at these joint positions, and these joint positions will not be reinforced with a reinforcing frame or the like, It is possible to have strength. Further, if the bottom of the aquarium body A is reinforced in this way, the strength of the glass outer peripheral side wall 1 of the aquarium main body A will inevitably increase. The opening of 1d is also prevented, and there is no need to provide a reinforcing frame on the upper side of the water tank body A.

In the above embodiment, since the outer peripheral side wall portion 1 is formed of the four plate glasses 1a to 1d, there is an advantage that the manufacturing cost can be further reduced, but the present invention is not limited to this. However, for example, the outer peripheral side wall portion 1 may be integrally formed into a predetermined frame shape. In short, the outer peripheral side wall portion 1 may be made of glass. Further, in the present invention, the specific shape, material, etc. of the bottom plate portion 2 are not limited to those in the above embodiment, and the specific joining means with the outer peripheral side wall portion 1 can be arbitrarily changed in design. Is. In addition, the water tank according to the present invention is not specified in its specific size or use.
