Water is sent.

  When the water gun toy 1 further pulls the trigger member (operation member) 90 against the elasticity of the third elastic member 93, the front portion 115 of the engagement member 103 engages with the engagement edge 116, The engagement member 103 rotates about the support shaft 105 in the engagement release direction, that is, the clockwise rotation direction against the elasticity of the fourth elastic member 107. When the rear portion 113 of the engaging member 103 is disengaged from the engaged member 71 and the engagement is released, the pressure member 60 moves forward due to the elasticity of the first elastic member 77, as shown in FIG. Water in the launch chamber 58 is launched from the launch port 55. The pressure member 60 stops moving when the rear end 66 of the guide groove 63 abuts on the guide protrusion 65 of the upper half firing tube (slide member) 15.

  Even when the engagement member 103 is disengaged from the engaged member 71 and the engagement is released and the pressure member 60 moves forward, the trigger member (operation member) 90 is still pulled. As shown in FIG. 4, the piston member 128 is held in a state of moving upward, and the water in the firing chamber 58 does not return back into the cylinder part 121 via the water supply port 125. The water discharged from the launch port 55 is ejected in a bullet shape by the first inclined surface portion 56 and the second inclined surface 57 of the projectile 53.

As shown in FIG. 5, in the water gun toy 1, when the operation of the trigger member (operation member) 90 is released, the trigger member (operation member) 90 is notched 91 due to the elasticity of the third elastic member 93. The front part 115 of the engaging member 103 is disengaged from the engaging edge 116, and the push-up body 141 is also moved forward via the connecting rod (linking means) 143. When the push-up body 141 moves forward, the second inclined surface 142 also moves forward, so that the second inclined surface 142 moves away from the first inclined surface 140 of the sliding body 137. The sliding body 137 has a water inlet 1
Since the second elastic member 132 is elastic, it is moved to the opposite side of the water supply port 125, that is, downward. When the sliding body 137 is moved downward, the piston member 128 is also moved to the opposite side of the water supply port 125, that is, downward. Since the pressure member 60 blocks the water supply port 125, a negative pressure is generated in the cylinder portion 121, and the water in the storage chamber 25 of the water tank 9 flows into the water supply communication pipe 28, the water supply pipe 22, and the water reception communication pipe 32. Then, it passes through the communication port 124 and is supplied into the cylinder part 121.

  As shown in FIG. 1, in the upper case 10, guide protrusions 12 a and 13 a are slidably guided in guide grooves 42 b and 43 b of the lower case 40. As shown in FIG. 6, the upper case 10 is moved backward with respect to the lower case 40. Since the upper half launcher (slide member) 15 is attached to the upper case 10, the upper half launcher (slide member) 15 also moves rearward. When the upper half firing tube (slide member) 15 moves rearward, the pressure member 60 also moves rearward against the elasticity of the first elastic member 77 via the guide protrusion 65 and the rear end 66 of the guide groove 63. As the pressure member 60 moves rearward, the engaged member 71 also moves rearward. The engaged member 71 is in sliding contact with the upper portion of the engaging member 103 at the initial position, and rotates the engaging member 103 in the clockwise direction against the elasticity of the fourth elastic member 107. As the engagement member 103 rotates counterclockwise due to the elasticity of the fourth elastic member 107, the engagement member 103 is engaged with the rear portion 113 and the pressure member 60 is biased forward. That is, the initial state is restored.

  When the upper case 10 is moved backward, the upper half firing tube (sliding member) 15 is also moved backward, so that the front portion of the main firing chamber 51 is opened and the inside of the main firing chamber 51 can be seen. After the upper case 10 is moved rearward and the engaged member 71 of the pressure member 60 is engaged with the engaging member 103 of the trigger member (operation member) 90, the upper case 10 is in contact with the projectile 53. By moving forward, the upper half firing tube (sliding member) 15 is also moved forward, the opened front portion of the main firing chamber 51 is closed, and the firing chamber 58 is formed again.

  In this way, when the water gun toy 1 operates the trigger member (operation member) 90, the pressure member 60 also moves rearward via the engagement member 103, and at the same time, the piston member 128 moves to the water supply port 125 side. The water in the cylinder part 121 is sent into the firing chamber 58, the engagement of the engagement member 103 with the pressure member 60 is released, and the pressure member 60 moves forward by the elasticity of the first elastic member 77, Water in the launch chamber 58 is launched from the launch port 55. When the operation of the trigger member (operation member) 90 is released, the trigger member (operation member) 90 and the piston member 128 are restored to the original state by the elasticity of the third elastic member 93, and water is stored in the cylinder portion 121. It is done. When the upper case 10 is reciprocated, the pressure member 60 is engaged with the engaging member 103 of the trigger member (operation member) 90 via the upper half firing tube (sliding member) 15 to return to the initial state.

  Another embodiment of the water gun toy according to the present invention will be described with reference to FIGS. FIG. 9 is a side sectional view for explaining another embodiment of the water gun toy according to the present invention. FIG. 10 is a perspective view for explaining another embodiment of the water gun toy according to the present invention. In the above embodiment, the pressure member 60 is biased by using the pulling force of the first elastic member 77. However, as shown in FIG. 9, the pressure member 60 uses the pressing force of the first elastic member 145. Of course, it may be energized. That is, a guide hole 146 is formed in the front-rear direction in the engaged member 71 attached to the pair of protrusions 69 and 70 formed in the lower rear portion of the pressure member 60. The engaged member 71 is slidably inserted into the guide hole 146 in the guide shaft 149 so that it can slide in the front-rear direction along the guide shaft 149. The guide shaft 149 is fixedly attached in the lower case 40, and a spring receiving portion 150 is formed at the rear. The first elastic member 145 is wound around the guide shaft 149 between the engaged member 71 and the spring receiving portion 150, and biases the pressure member 60 toward the launch port 55 via the engaged member 71. .

  In the above embodiment, the water storage tank 9 is detachably attached to the upper case 10, but the water tank 152 may be detachably attached to the lower case 40 as shown in FIG. If it does in this way, the storage chamber 25 of the water tank 152 and the inside of the cylinder part 121 will be directly connected by the communication port 124, and the water supply pipe 22 will become unnecessary.

  As shown in FIG. 11, the tip 61 of the pressure member 60 can form bullet-shaped polka dots almost certainly when the apex angle a is in the range of 60 ° to 90 °. In the water gun toy 1, the probability of forming polka dots was low when the apex angle a of the tip 61 was 91 ° or more, and a phenomenon in which small polka dots were dispersed when the angle a was 59 ° or less. In addition, the same result was able to be obtained even if the vertex was cut a little. Further, even if the first inclined surface portion 56 toward the launch port 55 does not exist, a bullet-shaped polka dot can be formed almost certainly.

  As shown in FIG. 12, when the inclination angle b of the first inclined surface portion 56 is in the range of 5 ° to 7 °, the flying distance of the bullet-shaped polka dots can be improved. In the water gun 1, a flying distance is not generated when the inclination angle b of the first inclined surface portion 56 is 4 ° or less, and when the inclination angle b is 8 ° or more, a phenomenon of dispersing polka dots occurs. As shown in FIG. 12 (b), if the second inclined surface portion 57 is not present, the tip becomes a sharp edge, and the shape of the launch port 55 is not constant under molding conditions (burr / short occurrence). Certainty is impaired. As shown in FIG. 12 (c), when the wall thickness 59 is formed, the certainty of polka dot formation is improved, but the flight distance is not generated. As shown in FIG. 12A, when the second inclined surface portion 57 is formed, the reliability of polka dot formation is improved and the flight distance is increased.
