Description

[Detailed description of the invention] [Technical field of the invention] The invention is a toy imitating the shape of an animal or other appropriate article, or a piston (pressure valve) built into a water storage tank attached to the main body so as to be able to slide freely. This relates to a water gun toy that, when pressed, sprays water from the tip of a nozzle connected to a water discharge opening formed in a part of the toy or main body.

[Prior art and its problems]

Actuated toys include those that are constructed so that the toy itself performs all of its functions after only being given a force to operate, and those that are constructed so that the toy itself performs all its functions after being given a firm force to perform its operation, and those that are constructed so that the toy itself performs all functions after being given a force to perform its operation. There are some people who cannot fully demonstrate their abilities. The former type of toy, such as a traveling toy, requires only a tightening operation (switching operation) to operate a screw or other power source, and is intended exclusively for use by young children with a low intellectual level, and is similar to a water gun. The latter cannot be effective unless the child activates its function, and is intended for use by children who are older than the former.

Many such water guns themselves are already known, and those with various structures are provided.

However, the structure of these water guns is that near the tip of the cylinder, which slides a piston mechanism (pressure valve) for moving water, there is a water intake port that is operated by opening and closing the valve, and a water intake port that is operated by opening and closing the valve. It has a structure that includes a water spout that is operated by opening and closing, and when the piston mechanism described above performs the action of sucking up water to retract (raise) the cylinder, the water intake valve mechanism described above opens and the water is discharged. The valve mechanism of the water spout is closed, and conversely, when the piston moves forward, the valve mechanism of the water spout opens and the valve mechanism of the water suction mechanism is closed. was common.

For this reason, even in the case of water guns, which are said to have a simple structure, the parts that make up them are
At least a cylinder, a pressure valve (piston),
Not only a valve mechanism on the water suction side and a valve mechanism on the water outlet side are required, but also valve housing parts are required.

As mentioned above, in the case of conventional water guns, since there are a large number of parts to construct them, the number of assembly steps is naturally increased, which inevitably leads to a rise in manufacturing costs and a high unit price. It has the disadvantage of being unavoidable.

Therefore, the members constituting the above-mentioned valve mechanism may have a structure such as a sphere or a lid, and among these, a sphere can be mentioned as a component that can be easily obtained. Since steel balls are mainly used for the parts, there is a problem of rust caused by oxidative corrosion due to contact with water, and the appearance of unevenness due to oxidative corrosion on the surface of the steel balls reduces the sealing ability of the valve mechanism. There was a problem of decline.

Furthermore, in the case of these conventional structures, mechanically there are many moving parts, which tends to cause variations in the fit of the mating parts, which often results in malfunctions. had some shortcomings.

[Purpose of invention]

In view of these circumstances, the present invention aims to deal with this problem, and one of the purposes is to reduce the number of parts used by simplifying the mechanism, thereby reducing the number of parts used. The aim is to provide water gun toys at low cost.

Furthermore, another purpose of the present invention is to simplify the mechanism to prevent malfunctions caused by variations in the performance of the parts used, and to reduce the influence of external forces on the component parts. The purpose of the present invention is to provide a water gun toy that is less likely to malfunction.

[Key points of the idea]

The present invention has a cylinder part for sliding a piston (pressure pump) on the bottom plate of a water storage tank that is installed inside a toy or main body, and the upper end of the cylinder part projects into the water storage tank by a small amount of height. By cutting out a part of the circumferential wall of the protruding cylinder, the cylinder is constructed and installed so that water in the water storage tank can naturally flow in, and the cylinder part and the water storage tank are integrated, and the cylinder is The key point of the invention is to draw out a water hose of an appropriate length from the lower end of the system, and to connect a water jet nozzle to the tip of the hose.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The water gun toy shown in this embodiment is constructed by incorporating a water gun mechanism A into the inside of the toy body 1 which is formed to resemble the appearance of an elephant.

The toy or main body 1 is constructed using a relatively hard synthetic resin, and is made by polymerizing mating molds 11, 11 that are configured to be split into two vertically from the center along the length direction. It is formed to have the appearance of an elephant with an extended trunk, and inside thereof, a large number of locking ribs 12 . . . 12 for attaching the water storage tank 2 of the water gun mechanism A are formed vertically and horizontally.

Reference numerals 13 and 13 denote handles formed above and integrally with the mating molds 11 and 11 that constitute the toy and the main body 1, and the assembled handles 13
There is a water inlet 14 inside the part surrounded by
A cylindrical opening 15 is opened above the opening, into which a piston 4 forming a part of the water gun mechanism A is inserted and slid. Note that the cylindrical opening 15 described above is desirably formed to have such a length that it can serve as a guide when the piston 4 is inserted and slid, and can guide its proper vertical movement. . Reference numerals 16 and 16 are drainage holes formed at the lower end of the toy or main body 1, which prevents water overflowing from the water storage tank 2 from remaining in the toy or main body 1, thereby maintaining the toy or main body 1 in a sanitary manner. It's planned like this.

The water gun mechanism A includes a water storage tank 2, a cylinder 3 whose upper end protrudes above the bottom plate 21 of the water storage tank 2 by a certain height, and most of the length thereof projects onto the lower surface of the water storage tank, as described above. The cylinder 3 is configured with a piston 4 that slides up and down inside the cylinder 3, and the peripheral wall of the cylinder 3 protruding above the bottom plate 21 has a notch 31 for guiding the inflow of water, which has a length that reaches the bottom plate surface. , 31 are formed vertically.

The piston 4 has a shaft rod 41 with a thick outer diameter at the part exposed on the top surface of the toy or main body 1, and a cap body 42 for pressing is formed at its upper end, and also slides inside the cylinder 3. A shaft rod 43 with a thin outer diameter is used for this portion. A rubber valve body 44 is attached to the tip of the shaft rod 43.

Note that the configuration of the shaft rod for constructing the piston 4 described above is not limited to the structure in which both the thick diameter shaft rod 41 and the thin diameter shaft rod 43 are used as in the embodiment. It is also possible to use only one shaft rod of the same diameter and attach the valve body 44 to the lower end thereof.

32 is a water spout formed at the bottom of the cylinder 3, which is formed in a cylindrical shape and is connected to a water discharge hose 33 for guiding the water spouted from the spout 32 to the outside. . The distal end of the water spraying hose 33 is connected to a spout nozzle 34 fixed to the tip of the elephant's trunk formed on the toy or main body 1.

5 is a spring for returning the piston 4;
It is elastically attached so as to span between the lower surface of the valve body 44 and the back surface of the bottom plate surface of the cylinder 3.

[Operation of the idea]

The present invention constructed as described above operates as follows.

In use, water is supplied to the water storage tank 2 through the inlet 14 opened on the top surface of the toy or main body 1.

Water is sufficiently supplied to the water storage tank 2, and the overflowing water is drained from drain holes 16...16 formed on the lower surface of the rice cake or main body 1, so that no excess water remains.

Since the piston 4, which is configured to slide up and down within the cylinder 3, is always urged upward by the force of the spring 5,
When water is supplied to the water storage tank 2, the cylinder 3
Water naturally flows into the cylinder 3 through notches 31, 31, which are vertically formed in the peripheral wall of the portion of the water storage tank 2 that protrudes from the bottom plate 21 surface.

When the piston 4 is lowered in a state where the cylinder 3 is filled with water flowing into the cylinder 3, the valve body 44 attached to the tip of the shaft rod 43 and the inner wall surface of the cylinder 3 are lowered below the bottom plate 21 surface. The water inside the cylinder 3 is forcibly pushed down by the pumping action caused by the sliding friction between the cylinder 3 and the water discharge port 32 formed at the lower end, passes through the water discharge hose 33, and reaches the spout nozzle 34, where the water is spouted to the outside. It can function as a water gun by doing this.

After spouting water, if the downward force of the piston 4 is released, the piston 4 is automatically returned to its original position by the return force of the spring 5, and is ready for the next operation. Thereafter, water can be spouted continuously by repeating the same operation as described above.

[Effect of idea]

The features of the present invention configured as described above are listed below.

(1) The structure of combining two mechanisms, a water intake valve and a spout valve, as seen in conventional water guns, is completely omitted, and the water stored in the water storage tank 2 is pumped into the cylinder 3 by using the head difference. Since the water gun is structured to allow water to flow into the water, the number of parts that make up the water gun can be significantly reduced and the structure can be simplified.

(2) As a result of reducing the number of parts, the number of assembly processes has been drastically reduced, making it possible to reduce manufacturing costs to an extremely low level.

(3) By reducing the number of parts and simplifying the configuration, we have been able to reduce the number of moving parts, which naturally makes it possible to reduce the number of parts where failures occur, and to extend the product life. We were able to provide long-lasting products at low prices.

(4) The material of the spring 5 is not particularly limited; for example, even if SUS is used as the material, there is no risk of malfunction of the pump due to rust due to the purpose of the member, but the material used for this If it is made of synthetic resin, it is possible to eliminate the need to use metal for all the constituent parts, so there is no need to worry about the parts corroding due to rust, and there is no need to worry about the mechanical parts that are caused by corrosion. There is no need to worry about malfunctions, and the features of the structure can be brought out even more effectively.

(5) By imitating the shape of the toy or main body 1 to resemble an animal or other shape, the water spray from the water spray hose 33 can be simulated in an interesting manner of operation; Hose 3
By changing the connection part 3, it is possible to provide a water gun toy that is even more interesting.
