Abstract

PURPOSE: To provide a floating underwater toy capable of attracting much attention via the application of very pimple constitution by superposing a plurality of closed cell foamed resin sheets on top of one another in many layers, integrally jointing the resin sheets to one another with a weight member clamped between each layer and, then, forming the toy so as to stand up in such a state as freely vibrant and displaceable with the lower end approximately in contact with the bottom of the water and buoyancy acting on the upper end. CONSTITUTION: A toy body 10 formed to have a fish shape out of a closed cell foamed resin material is made of a plurality of superposed layers of closed cell resin sheets 12a, 12b and 12c, each having the prescribed thickness, and the layers are integrally jointed to one another at a thermal fusion process. A cutout section 14 is formed on the intermediate closed cell resin sheet 12c at such a position as properly maintaining a downward gravity balance, and the prescribed weight 16 is coupled to the section 14. According to this construction, the floating underwater toy body 10, when thrown into water in a tank, a swimming pool or the like, has the lower end thereof approximately in contact with the bottom of the water, and takes a standing posture. Furthermore, the body 10 becomes afloat with buoyancy acting on the upper end thereof and positioned in water in such a state as vibrant and displaceable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating underwater toy that can be oscillated and displaceable at the bottom of a water tank when placed in a water tank.

[0002]

2. Description of the Related Art Generally, a floating underwater toy of this type is known which is made of various plastic materials having a shape imitating fish, shellfish, crustaceans, other animals and the like. This type of toy, for example, formed into a container,
By filling the inside with water, it is configured to float up and down in water, or by being formed of a foam, it is configured to change the buoyancy by absorbing water. In addition, those that are not provided with pores or hollow portions remain in a state of being sunk on the bottom surface of the water tank.

From this point of view, in order to obtain a more entertaining underwater toy, a closed cell resin shrinkage body is housed and arranged inside the toy body having a proper ups and downs so that it can communicate with the outside. However, by reducing the water pressure inside the water tank outside the toy body, the closed-cell resin contractile body is restored and expanded, so that the toy is propelled in water by the water flow discharged to the outside of the toy body. Has also been proposed (Japanese Patent Laid-Open No. 1-178284).

[0004]

However, the above-mentioned conventional floating underwater toys, which are configured so that the buoyancy can be simply changed, either remain floating on the water surface or sink on the bottom surface of the water tank. Although it remains as it is, the manufacturing cost can be reduced, but it is extremely less interesting as a toy.

Further, the toy itself configured to generate a propulsive force is rich in interest, but not only increases the manufacturing cost due to the complicated structure, but also decompresses the water tank itself. Since it is necessary to install a device and the like, there is a drawback that equipment cost also increases.

Therefore, an object of the present invention is to use a closed-cell resin material having a shape imitating fish, shellfish, crustacean, other various characters, toys, etc. It is an object of the present invention to provide a floating underwater toy with a very simple structure and abundantly entertaining, which can be almost brought into contact with the bottom of the water and can be oscillated and displaceable in a balance relationship with buoyancy.

[0007]

In order to achieve the above object, the floating underwater toy according to the present invention has a plurality of closed-cell resin plates stacked in multiple layers, and a weight member is sandwiched between the closed-cell resin plates. It is characterized in that these are integrally joined to each other, and that the lower end thereof substantially abuts on the bottom of the water and the upper end thereof is buoyantly erected so as to be swingably displaceable.

In the above floating underwater toy, the closed-cell resin plate has a three-layer structure, a cutout portion is provided in the closed-layer closed-cell resin plate of the intermediate layer, and a weight plate made of a stainless steel plate is fitted into the cutout portion. The closed cell resin plates may be integrally joined by heat welding.

Further, the floating underwater toy of the present invention can be used for fishing games by providing a through hole in a part of the closed-cell resin plate integrally joined and attaching a ring member to the through hole. it can.

[0010]

The floating underwater toy according to the present invention, when placed in water, causes the lower end of the toy to substantially contact the bottom of the water, and the upper end of the toy floats up due to the action of buoyancy and can be oscillated and displaced in water. It will be in a standing state.
Therefore, when diving and picking up this toy, the position of the toy located at the bottom of the water is displaced according to the rocking of the water, and the toy moves as if it were automatically propelled. It will be rich.

The floating underwater toys according to the present invention obtained by the respective embodiments described above are put into a water tank, a pool or the like so that the lower end portions of the toys come into contact with the bottom of the water, respectively. As shown in each (a) figure of FIG. 4, it will be in the standing state. That is, the upper end portion of each toy floats up by the action of buoyancy and is positioned so that it can be swung and displaced in water.

Therefore, the floating underwater toy according to the present invention is
By providing through holes 20 in a part of the upper end side of the toy body 10 (see FIGS. 1 to 4), and attaching a ring-shaped member (not shown) to each of these through holes 20, fishing is performed. It can also be used as a floating underwater toy for games.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-mentioned embodiment. For example, a closed cell resin plate having a closed cell polyethylene foam having a different cell expansion ratio (30 times product). Etc.) and other materials, and the weight members other than the stainless steel plate can be used, and the dimensions and weights thereof can be changed in design. In the present invention, the cellular resin plate has a two-layer structure, and a pullout portion is provided on one side of the cellular resin plate so that a weight plate or the like can be inserted and held therein, or the toy body is formed as a three-dimensional object instead of a flat body. Various design changes can be made without departing from the spirit of.

[0022]

As is apparent from the above-described embodiments, the floating underwater toy of the present invention is constructed by stacking a plurality of closed-cell resin plates in multiple layers and holding a weight member between the layers of the closed-cell resin plates. These are integrally joined together, and the lower end almost contacts the bottom of the water in water and the upper end is buoyant so that it can swing and displace. When a toddler or the like dives and picks it up, the position of the toy located at the bottom of the water moves according to the rocking of the water, so that the toy moves as if the toy is automatically propelled. Therefore, it will be extremely entertaining.

Further, the floating underwater toy of the present invention having the above-mentioned structure can be used as an ornamental accessory because it can be oscillated and displaced in accordance with the sway of water in a standing state. It can also be widely used as a toy for games such as fishing.

Further, the floating underwater toy according to the present invention is
Since the structure is simple, it is easy to manufacture and can be mass-produced at a relatively low cost. Moreover, since it can be manufactured from a material having a high structural safety, it is effective and interesting as a toy for infants, and has many excellent advantages.
