The launching device 8 is adapted to be engaged with the injection nozzle portion 2 of the water-jet type traveling toy 20 in a state of being closed by closing the injection nozzle portion 2 and being engaged with the injection nozzle portion 2. It can be set to a disengaged state in which the jetting nozzle portion 2 is opened by releasing the jetting and the jetting of water is enabled.

As shown in FIG. 4, this launching device 8 is constructed by attaching an air injection valve for a bicycle tire as an air pressure injection valve 7 to a receiving side member of a one-touch connection type hose joint (FIG. 4). Regarding the structure of the hose joint, see JP-B-63-29155).

In this example, the rear end of the firing device 8 is sealed by the air pressure valve 7, and air can be pressed into the pressure vessel 1 from the air pressure valve 7 via the firing device 8.

The launching device 8 has a receiving port 40,
When the spigot 28 of the injection nozzle portion 2 is inserted into the receiving port 40, the engaging means 9 engages with the engaging groove 28 of the spigot 27 to prevent the spigot 27 from coming out. A retaining member 38 is provided. The retaining member 38 is in contact with a sliding member 39 attached to the outside of the receiving port 40 so as to be able to move forward and backward.

As shown in FIG. 4, the retaining member 38
It is a claw-shaped member that projects its tip into the receptacle 40 in contact with the sliding member 39. The retaining member 38 is elastically deformed when the spout 27 of the injection nozzle portion 2 is inserted, and
Can be inserted, and the injection nozzle portion 2
In a state where the ejection nozzle portion 2 is completely inserted into the engagement groove portion 28, the ejection device 8 is in an engagement state in which the ejection nozzle portion 2 does not come off.

The sliding member 39 is an annular member. The sliding member 39 is constantly urged by the spring 41 toward the injection nozzle (in the direction of arrow D in the drawing), and the state in which the retaining member 38 is engaged with the engaging groove 28 is shown. keep. This allows the launching device 8 to move the water-injection traveling toy 2
0 is attached to the injection nozzle 2
To keep the engagement state.

When the sliding member 39 is moved in the direction opposite to the urging direction by the engagement releasing means 10, the retaining member 38 is opened outward to release the engagement with the engaging groove 28, and the firing device is released. Reference numeral 8 denotes a disengagement state in which the engagement with the injection nozzle portion 2 is released.

In this embodiment, the engagement release means 10 is configured to be capable of being remotely operated. Disengagement means 10
Connects the operation handle 42, the slide member 43 connected to the slide member 39 and slides the slide member 39 with respect to the firing device main body, and connects the operation handle 42 and the slide member 43 to each other. And an operation wire 44 for transmitting the operation of the handle 42 to the slide member 43.

The operation handle 42 includes a grip portion 45,
A lever 46 is supported by the grip 45. Reference numeral 47 denotes a stopper for preventing erroneous operation. The configuration of the remote control device is not limited to this example, and various configurations having a similar function can be selected.

The operation wire 44 includes a wire 48 and a covering member 49. One end of the covering member 49 is connected to the grip portion 45, and the other end is connected to the substrate 50 attached to the firing device 8. One end of the wire 48 is connected to the lever 46 of the operation handle 42, the other end is extended to the slide member 43, and a stopper member 51 is provided at the end.
Are fixed with screws 52. The slide member 43 is an annular member provided around the slide member 39, and has a wire locking portion 53 for locking a stopper member 51 fixed to the tip of the wire 48.

According to the engagement releasing means 10, when the lever 46 of the operation handle 42 is pulled toward the grip 45, the wire 48 is pulled, and the slide member 43 slides toward the substrate 50. By the operation of the slide member 43, the slide member 39 of the firing device 8 moves together with the slide member 43, and the firing device 8 is brought into the disengaged state in which the engagement with the ejection nozzle portion 2 is released.

In order to launch and run the water-jet traveling toy 20 according to the present embodiment, first, an appropriate amount of water is poured from the injection nozzle 2 into the pressure vessel 1 of the water-jet traveling toy. If the amount of the water is too large, the amount of air to be compressed and enclosed decreases, the momentum of the water spouting quickly diminishes, and the traveling speed and traveling distance of the water-jet traveling toy decrease. On the other hand, if the amount of water is too small, the water to be jetted quickly disappears, and similarly the traveling speed and the traveling distance decrease.

Next, the spigot 27 of the jet nozzle portion 2 of the water jet type running toy 20 is inserted and connected to the receiving port 40 of the firing device 8 to bring the firing device 8 into an engaged state. Then, air is injected into the pressure vessel 1 of the water-jet traveling toy 20 from the air injection valve 7 of the launching device 8 by air injection for the bicycle. Thereafter, the water injection type traveling toy 20 is disposed at a predetermined position where there is no obstacle on the traveling path, and the lever of the operating handle 42 of the disengaging means 10 is provided at a location where the water jet from the water injection type traveling toy 20 is not applied. Operate 46.

That is, the lever 46 of the operation handle 42 is pulled toward the grip, the wire 48 is pulled, and the slide member 39 is slid together with the slide member 43 toward the substrate 50. When the sliding member 39 is moved in the direction of the substrate 50, the firing device 8 is disengaged, and the retaining member 38 located inside the sliding member 39 can be opened outward and engaged with the retaining member 38. The engagement with the groove 28 is released. Then, the water in the pressure vessel 1 is compressed by the pressure of the compressed air into the nozzle holes 3.
And the water-jet-type traveling toy 20 travels by the reaction of the water injection. When the water in the pressure vessel 1 is stopped, the surface of the water is horizontal, but the water moves to the rear of the pressure vessel 1 due to the acceleration at the start of the water-jet traveling toy 20, so that almost all of the water is in the nozzle hole. 3 will be injected.

Therefore, according to the water-jet type running toy according to the present embodiment, since the propulsion force is obtained by jetting water and air, and the toy can be made to run vigorously, it is safe and interesting. high. According to the test of the present inventor, a water-jet type running toy was prepared using a 1.5 liter plastic bottle as the pressure vessel 1, and 1 liter of water was put inside the pressure vessel 1 and the bicycle was filled with air. 4 air in pressure vessel 1
When it was sealed and fired at ５5 atm, it traveled about 30 to 40 m.

In this embodiment, since the disengagement device 10 can change the firing device 8 from the engaged state to the disengaged state by remote control using the operation handle 42 and the operation wire 44, the water-jet type running toy is provided. The firing operation can be performed in a place where the water sprayed by the jet 20 does not splash.

Further, in this embodiment, since the nozzle hole 3 of the injection nozzle portion 2 is slightly obliquely directed downward, the water-injection type traveling toy 20 of this embodiment blows water upward to break the posture. It runs well without becoming.

Further, in this embodiment, since the cushion member 13 is provided, even if it collides with another article or the like during traveling, the impact given to the other party can be reduced and the traveling toy can be prevented from being damaged.

Further, in this embodiment, since the opening area of the nozzle hole 3 is variable, the running state of the water-jet type traveling toy 20 can be changed by changing the opening area of the nozzle hole 3. If the opening area of the nozzle holes 3 and 37 is increased, a large amount of water can be sprayed in a short time, and the acceleration at the time of firing can be increased. Water can be sprayed over time, and traveling can be performed for a long time.
