Real Fair 7-463

The valve body that allows water to enter into the housing portion of the conventional migrating toy may be deformed by the internal pressure, and may not function normally as the valve body. In addition, the conventional migrating toy has a large accommodating portion with respect to the size of the foaming agent, and the foaming agent is accommodated in the accommodating portion to take in water. The foaming agent generates bubbles when placed in water, and irregularly moves inside the container as the bubbles are generated. Thus, if the foaming agent moves irregularly within the housing part, the center of gravity position of the electrophoresis toy changes due to the buoyancy of the foaming agent, etc. It was.
The present invention has been made in view of the above problems , and it is a first object to provide a propulsion toy having a water intake valve that functions normally and does not deteriorate its function as a valve. And It is a second object of the present invention to provide a propulsion toy that can be advanced in a normal posture without breaking the balance on the water surface by regulating the loosening of the foaming agent in the accommodating portion inside the main body.

In the propulsion toy according to the present invention, the valve body of the water intake valve is formed by superimposing the flexible first plate and the rigid second plate, so that the valve body is deformed. This prevents the valve body from being arranged so that the first plate can come into contact with the hole, thereby improving the adhesion of the valve body.
Moreover, since it has the structure which controls the movement of the accommodated foaming agent, the said foaming agent can move freely and can advance the water surface, without the attitude | position of the said propulsion toy being destroyed by the buoyancy of the said foaming agent. It has the effect.
Further, since the regulating member that regulates the loosening of the foaming agent is formed so as to surround the outer periphery of the foaming agent, it is easy for the user to confirm the place where the foaming agent is disposed.
Moreover, since it has an air holding part having buoyancy at the top of the propulsion toy and a weight provided at the bottom, the posture of the propulsion toy further collapses in addition to the action due to the movement restriction of the foaming agent. Can be prevented.
The propulsion toy according to the present invention can also be used as a toy for a bath, but if it is submerged in water, there is a possibility that a child will step on it by mistake. However, since the propulsion toy according to the present invention has a buoyancy that does not sink in the water by the air holding part, it has the effect that it does not sink into the bottom of the bath and is not stepped on by children.

Hereinafter, the best mode of the propulsion toy according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of the propulsion toy 1 according to the present embodiment, FIG. 2 is an exploded perspective view of the propulsion toy 1 as a whole, and FIG. 3 is an exploded view of the mounting body 2 constituting a part of the propulsion toy 1. It is a perspective view.
The propulsion toy 1 has a foaming agent 3 that generates a gas such as carbon dioxide when in contact with water, and a container 4 with a predetermined volume that stores water taken from outside, and the gas generated in the container 4 The toy is configured to inject the taken-in water to the outside by the pressure of and to advance the water surface by the propulsive force accompanying the injection of the water. The propulsion toy 1 includes, as main components, a lower outer shell body 5 having the housing portion 4 provided on the inner side thereof, and the mounting body 2 detachably mounted on the upper portion of the lower outer shell body 5. ing.

The lower outer shell 5 is a member that forms a lower portion of the propulsion toy 1 formed in the shape of a rounded ship, and is formed by integral molding of synthetic resin.
The lower outer shell 5 includes a bottom wall 19, a left side wall 16, a right side wall 17, and a rear side wall 18 erected upward so as to surround the bottom wall 19. It is a container-like member in which an opening 15 is formed as an opening edge. The opening 15 and the bottom wall 19 have a tapered front portion that becomes the bow as compared with the rear portion that becomes the stern in a plan view, and the opening 15 is formed slightly longer in the front / rear (forward / stern) direction than the bottom wall 19. Has been. The lower outer shell 5 is a space (accommodating a predetermined volume) surrounded by the left and right and rear side walls (16, 17, 18) having the peripheral edge of the opening 15 as the upper edge and the bottom wall 19 constituting the ship bottom. Part 4). The thickness of each side wall is formed to be approximately 1 to 2 mm.
Further, two small holes 13 are formed below the rear side wall 18. The small hole 13 is a hole that communicates the inside and the outside of the housing portion 4. When the internal pressure of the housing portion 4 increases, the small hole 13 blows water to the ejection means to be described later to propel the propulsion toy 1. It is what has.

At the approximate center of the bottom wall 19 which is the bottom of the lower outer shell body 5, there is provided an opening 6 communicating with the outside and a water intake valve 7 by a valve body (disks 21 and 22) which closes the opening 6 so that it can be opened and closed. It has been. The water intake valve 7 has a cylindrical housing part 20 that is formed integrally with the bottom wall 19 and protrudes in the direction of the accommodating part 4. In the housing part 20, the end part on the housing part 4 side is closed by the wall part 40, but the end part on the bottom wall 19 side is opened to form an opening 41, and the housing part A plurality of holes 42 are formed in the side wall 20 so as to communicate the accommodating portion 4 and the inside of the housing portion 20. The opening 6 communicates with the accommodating portion 4 through the plurality of holes 42 and the opening 41. Further, the water intake valve 7 includes two disks 21 and 22 that are arranged to be movable up and down in the housing part 20, and the housing part 20 that houses the two disks 21 and 22. The lid member 23 is used to close the opening 41. The two overlapped discs 21 and 22 are plate-like bodies having substantially the same diameter, and the disc 21 located on the upper side is formed of a material having rigidity that is at least a specific gravity greater than that of water. In this embodiment, iron is used as a material. The disk 22 positioned below the stacked disks is made of a material having elasticity, and a material such as rubber is used in this embodiment.
A lid member 23 that closes the opening of the housing portion 20 is provided with a circular hole 24 having a smaller diameter than the disk 22. The circular hole 24 is a portion that serves as an intake port for water that flows into the accommodating portion 4 from the outside. The circular hole 24 is blocked by the contact of the disk 22 and water into the accommodating portion 4. The inflow is prevented, and the inflow of water into the accommodating portion 4 is allowed by releasing the contact. That is, the periphery of the circular hole 24 serves as a valve seat, and the discs 21 and 22 come into contact with the valve seat as valve bodies, thereby fulfilling a function as an on-off valve that controls the inflow of water into the housing portion 4. Yes.

The vertical movement of the two discs 21 and 22 is performed by a pressure difference between the inside and the outside of the accommodating portion 4 in the circular hole 24 portion, and when the pressure in the accommodating portion 4 is lower than the outside, the disc 21 and 22 ascend to allow inflow of water through the circular hole 24, and when the pressure in the accommodating portion 4 is higher than the outside, the disks 21 and 22 block the circular hole 24 and inflow of water. To come to a limit.
In addition, as described above, the disc that is the valve body is formed by superposing the iron disc 21 and the rubber disc 22 as described above. In this embodiment, the iron disc 21 and the rubber disc 22 are accommodated in the housing portion 20 in a separated state. However, the iron disc 21 and the rubber disc 22 are bonded together. Etc., and may be integrally configured and accommodated.

The reason why the iron disc 21 which is a metal having high rigidity and the rubber disc 22 having elasticity are overlapped and accommodated is as follows.
The discs 21 and 22 that serve as valve bodies are pressed around the circular holes 24 of the lid member 23 that serves as the valve seat under the internal pressure of the accommodating portion 4. However, if the valve bodies do not have rigidity, they are normal as valve bodies due to deformation due to the internal pressure. Therefore, the valve body is required to have a predetermined rigidity. On the contrary, if the rigidity is simply high, the adhesiveness with the valve seat is lowered, so that a gap is formed between the valve seat and the function as a valve is lowered. In view of this property, in the water intake valve 7 according to the present embodiment, a flexible rubber disc 22 is used for the valve body in contact with the periphery of the circular hole 24 serving as a valve seat, and the internal pressure of the accommodating portion 4 is increased. In order to prevent the disk 22 from being deformed even if it is received, a highly rigid disk 21 is stacked on the disk 22.

  Further, since the water intake valve 7 operates quickly even with a slight pressure difference in the accommodating portion 4 and needs to take in a predetermined amount of water in a short time, the circular hole 24 serving as a water intake is relatively large. The disk 22 that is formed and closes the circular hole 24 is also formed to be large in accordance with the opening area of the circular hole 24. The increase in the area of the disk 22 means that the force received is increased and the degree of deformation is increased, but in the present embodiment, in view of such a point, rigidity is required for preventing deformation. The high disk 21 is used together.

The reason why the disk 22 is made of metal such as iron as described above is to prevent the disk 21 from being deformed and to bring the disk 21 into contact with the periphery of the circular hole 24 by its own weight. is there. This is because when there is no pressure difference between the inside and outside, the disks 21 and 22 are in contact with the periphery of the circular hole 24 as an initial position. As will be described in detail later, water can be efficiently injected.
Further, weights 8 are respectively attached to the front and rear of the bottom wall 19 of the lower outer shell body 5. The weight 8 lowers the position of the center of gravity of the propulsion toy 1, maintains the posture of the propulsion toy 1 floating on the water surface, and keeps the bottom wall 19 always immersed in the water. This is to smoothly take in water.

A plurality of plate pieces 25 are arranged at regular intervals around the housing part 20 described above, which is located at the approximate center of the bottom wall 19 of the lower outer shell 5 so as to surround the housing part 20. . In other words, the plate piece 25 forms a circular accommodating space 26 in the bottom wall 19 with an upper opening. The housing space 26 is a space for housing the solidified foaming agent 3, and the movement of the foaming agent 3 in the front-rear and left-right directions is regulated by the plate pieces 25. In addition, since the upper part of the accommodation space 26 is also blocked | closed by the bottom wall 43 of the control member 33 provided in the mounting body 2 by mounting | wearing the mounting body 2 mentioned later, the up-down direction of the foaming agent 3 is carried out. Movement is also restricted within the accommodation space 26. These plate pieces 25 and the bottom wall 43 are regulating means for regulating the movement of the foaming agent. Further, the gaps between the plate pieces 25 and the plate pieces 25 are formed in such a size that they cannot pass through until almost all of the gas has been released and the outer shape of the foaming agent 3 has been reduced.
The foaming agent 3 is held at a position corresponding to the center of the hull for the following reason. That is, when the foaming agent 3 absorbs water and starts to generate gas, the foaming agent 3 irregularly moves inside the housing portion 4 due to an increase in the buoyancy of the foaming agent 3 and the jetting power of the gas accompanying the generation of the gas. This is to eliminate the phenomenon that the foaming agent 3 moves and the foaming agent 3 moves irregularly in the accommodating portion 4 so that the balance of the center of gravity of the hull is lost and the normal posture cannot be maintained. In order to prevent the occurrence of such a phenomenon, as a means for restricting the movement of the foaming agent 3, a housing space 26 for the foaming agent 3 constituted by a plurality of plate pieces 25 is provided.

A mounting body 2 formed as a design simulating the upper part of the hull is detachably attached to the upper part of the lower outer shell body 5 described above. Hereinafter, the structure of the mounting body 2 will be described in detail with reference to FIG.
The mounting body 2 has a predetermined volume of air holding portion 9 having a buoyancy that allows the migrating toy 1 to float on the water surface, an air valve 10 provided substantially at the center, and a water outlet 11 in the housing portion 4. Injecting means (nozzles) 12 for injecting the taken-in water toward the outside of the accommodating portion 4 is provided.
The mounting body 2 is formed by joining the upper half 27 constituting the upper part and the lower half 28 constituting the lower part, and the air holding part 9 having the predetermined volume is formed inside by the joining. ing. The upper half body 27 is similar in shape to the opening 15 of the lower outer shell body 5, and extends substantially vertically downward with respect to the upper wall 44 from the upper wall 44 that is slightly larger than the opening 15 and the periphery of the upper wall 44. A hole 29 is formed in the approximate center of the upper wall 44. The lower half body 28 includes a bottom wall 46 that is similar in shape to the upper wall 44 of the upper half body 27 and is slightly smaller, and a side wall 47 that is erected substantially vertically upward from the periphery of the bottom wall 46. An opening 48 is formed substantially at the center of the bottom wall 46, and a cylinder 49 is erected from the periphery of the opening 48 substantially perpendicular to the bottom wall 46. The upper half body 27 and the lower half body 28 are joined to the inner surface of the side wall 45 of the upper half body 27 in a state where the outer surface of the side wall 47 of the lower half body 28 is in close contact, thereby forming the mounting body 2. At this time, the hole 29 and the cylinder 49 are surrounded by the cylinder 49. In addition, at least the propulsion toy 1 is submerged in the mounting body 2 by the inner surface of the upper wall 44 of the upper half body 27, the inner surfaces of the bottom wall 46 and the side wall 47 of the lower half body 28, and the cylinder 49. A predetermined volume of air holding part 9 having a buoyancy of a certain level is formed.

An air valve 10 is provided in the center of the mounting body 2. The air valve 10 has a hole 29 provided in the upper wall 44 of the upper half 27 and a bottom wall of the lower half 28 from the direction of the bottom wall 46 of the lower half 28 so as to surround the hole 29. It has a restricting member 33 attached to 46 cylinders 49. The end of the regulating member 33 on the side not in contact with the upper wall 44 of the upper half 27 is closed by the bottom wall 43. The length of the regulating member 33 is such that the bottom wall 43 of the regulating member 33 is formed in the bottom wall 19 of the lower outer shell 5 when the mounting body 2 is attached to the lower outer shell 5. Are formed so as to reach the upper end (ie, the upper end edge of the plate piece 25). Further, a plurality of openings 51 are formed in the side wall 50 of the regulating member 33, and the housing portion 4 of the lower outer shell body 5 communicates with the outside of the propulsion toy 1 through the plurality of openings 51 and the holes 29. ing. Further, a hollow cylindrical float member 31 is accommodated in the regulating member 33 so as to be movable up and down, and the cross section of the float member 31 from the end surface on the hole 29 side is slightly larger than the float member 31. A cylindrical valve body 30 which is smaller and larger than the hole 29 is provided upright. The valve body 30 can take a position where the hole 29 is closed and a position where the hole 29 is opened as the float member 31 moves up and down within the regulating member 33.
Further, since the float member 31 is formed in a hollow shape, an air holding portion 32 is formed therein so as to have buoyancy with respect to water, and the buoyancy of the air holding portion 32 causes the inside of the housing portion 4 to be formed. The valve body 30 is moved up and down according to the water level.

  An upper small hole 54 is formed in the rear portion of the upper wall 44 of the upper half body 27, and an upper cylinder 55 is formed substantially vertically downward from the peripheral edge of the upper small hole 54 with respect to the upper wall 44 of the upper half body 27. The nozzle 14 is attached to the upper small hole 54 from the outer surface side of the upper wall 44 of the upper half 27. A lower cylinder 56 is formed at the rear of the bottom wall 46 of the lower half body 28 so as to penetrate the bottom wall 46, and the upper end of the lower cylinder 56 is formed by the upper half body 27 and the lower half body 28. When joined, the upper cylinder 55 is connected. When the mounting body 2 is attached to the lower outer shell body 5, the lower end of the lower cylinder 56 is included in the accommodating portion 4 of the lower outer shell body 5 and becomes the water outlet 11. The nozzle 14, the upper small hole 54, the upper cylinder 55, and the lower cylinder 56 communicate the housing portion 4 with the outside of the propulsion toy 1, and the water in the housing portion 4 taken in from the water outlet 11 flows from the nozzle 14. Erupts. That is, the nozzle 14, the upper small hole 54, the upper cylinder 55, and the lower cylinder 56 form the ejection unit 12.

In the present embodiment, the decorative body is a member formed in a design simulating a cockpit of a ship, and a hole provided on the bottom surface (not shown) is fitted with a circular protrusion 35 provided on the upper surface of the mounting body 2. Thus, it can be attached to the upper surface of the mounting body 2.
Further, locking means 36 having a function as a locking means are rotatably attached to the left and right side surfaces of the mounting body 2. The locking means 36 is a member formed in a disk shape, and is provided with a shaft 37 serving as a rotation center near the outer periphery and a notch 38 in a part of the outer periphery. The notch 38 of the locking means engages with protrusions 39 provided on the left and right side surfaces of the lower outer shell body 5 in a state where the mounting body 2 is mounted on the upper portion of the lower outer shell body 5. The removal of the mounting body 2 with respect to the outer shell body 5 is regulated. The shaft 37 is inserted into holes 40 formed in the left and right side surfaces of the mounting body 2 and is held rotatably.

  FIG. 4 shows a cross-sectional view of the propulsion toy 1. The state shown in FIG. 4 shows a state before the propulsion toy 1 is floated on water. In this state, since there is no water inside and outside the accommodating portion 4, the disk bodies 21 and 22 of the water intake valve 7 are lowered by their own weight, and the float member 31 of the air valve 10 is also lowered by its own weight and the valve is opened. It has become. The foaming agent 3 is in a state of being located in the accommodation space 26 surrounded by the plate piece 25 and the bottom wall 43 of the regulating member 33. The inside of the accommodating part 4 is filled with air.

  FIG. 5 shows a state in which the propulsion toy 1 is floated on the water and the water W starts to enter the accommodating portion 4. In the state shown in FIG. 5, the disk bodies 21 and 22 of the water intake valve 7 are pushed up by water pressure, and water is taken into the accommodating portion 4 through the opening 6 (circular hole 24). The float member 31 of the air valve 10 also rises as the water level in the housing part 4 rises. In the accommodating portion 4, water and air are mixed, and the foaming agent 3 is also submerged and begins to generate gas.

FIG. 6 shows a state where water is further taken into the accommodating portion 4 from the state shown in FIG. 5 and gas generation is also active. When the water level in the accommodating portion 4 rises, the float member 31 rises, so that the valve body 30 closes the hole 29, that is, the air valve 10 is closed, and then gas is generated from the foaming agent 3. Then, the gas bodies and air in the housing part 4 are in a state in which the disk bodies 20 and 21 block the opening 6 due to the pressure pushing the water surface, that is, the water intake valve 7 is also closed.
Furthermore, when the generation of gas from the foaming agent 3 proceeds and the pressure of the gas and air in the housing part 4 becomes higher than the atmospheric pressure outside the propulsion toy 1, the water housed in the housing part 4 passes through the water outlet 11. The propulsion toy 1 is advanced by being pushed out and blown out from the nozzle 14 as the jetting means 12 and a thrust in a direction opposite to the blowing direction is generated. Further, the foaming agent 3 tends to move irregularly with the generation of gas, but the movement range is limited within the accommodation space 26 by the action of the restricting means by the plate piece 25 and the bottom wall 43 of the restricting member 33. The

From the state shown in FIG. 6, when the water level in the accommodating portion 4 is lowered by the ejection of water, the float member 31 is also lowered, and the hole 29 and the valve body 30 are separated as the float member 31 is lowered. That is, since the air valve 10 is opened, the pressure of the air (mainly gas) in the housing portion 4 is lowered, and the water intake valve 7 is opened again by the external water pressure, and water is taken into the housing portion 4. And if the water level in the accommodating part 4 rises again, the water intake valve 7 and the air valve 10 are closed, and the operation | movement of ejecting the water W from the nozzle 14 is repeated.
In this way, the propulsion toy 1 is advanced on the water surface while alternately repeating the intake and ejection of water into the housing portion 4. The solid foaming agent 3 is held near the center of the hull until the foaming agent 3 is consumed and becomes small. Therefore, the above cycle is maintained without impairing the attitude of the hull until the gas emission of the foaming agent 3 is almost completed. The propulsion toy 1 can be advanced on the water surface while repeating the above.
