Description
- This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2007-116166, filed on Apr. 25, 2007, the entire contents of which are incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a toy ball which is used after it has been inflated by feeding air thereinto.
- 2. Description of Background Art
- Conventionally, there have been sold many toy balls of air injection type like a beach ball which is inflated by injecting air into an interior thereof for use, and there have been made many technical proposals with respect to these air injection type toy balls. As a common air injecting portion of the air injection type toy balls, a configuration is used widely in which a valve is formed at an inner end portion of a cylindrical air injecting port made of rubber or the like which is situated inside the ball for closing an opening in the cylindrical air injecting port. In this configuration, when air is injected from the air injecting port, the valve is opened towards the inside of the ball by the air so injected, while when no air is injected, the valve closes the air injecting port to prevent the leakage of air from the inside of the ball by virtue of the internal pressure inside the ball, and furthermore, a plug is fitted in the air injecting port from the outside so as to ensure that there is no air leakage from the toy ball.
- For example, Japanese Unexamined Patent Publication No. 2000-42142 proposes a configuration in which tooth-shaped projections are provided along a circumferential edge of an external lid as a plug, while tooth-shaped projections are also formed along an inner edge of an air inlet port in such a manner as to be locked with the projections on the external lid, whereby by tightly fitting the plug into the air inlet port, the outer lid which is the plug is strongly fixed in place in the air inlet port.
- In general, with the conventional air injecting portion, the air injecting portion also needs to be formed on a ball main body at the same time as the ball main body is formed, and this has made difficult the formation of the ball. In addition, since the valve needs to be opened using the pressure of air injected when air is injected into the ball, a large air pressure becomes necessary when air is injected, and this has made difficult the injection of air. Additionally, when air is discharged from the ball, the valve needs to be removed or displaced, and this has made difficult the discharge of air.
- In addition, while there exists a method in which a small hole is formed in a ball, a straw is passed through the hole for injecting air into the inside of the ball and when the injection of air is completed, the straw is removed and a plug is placed in the small hole, in this case, there has been caused a problem that air leaks out from the removal of the straw until the placement of the plug.
- The present invention has been made in view of the problems inherent in the related art, and an object thereof is to provided a toy ball which includes an air plug which is easy to shape and manufacture of the toy ball, as well as easy injection and discharge of air and which is easy to plug after air injection is completed.

- In addition, the air plug (3) includes a pipe-like air injecting pipe (32) having an enlarged portion at an outer end portion thereof, an air flow-in member (31) which is mounted at an inner end portion of the air injecting pipe (32) and which has a space in an interior thereof, and a spherical valve (33) which is inserted into the space in the air flow-in member (31) in such a manner as to be sorbable movable state to a distal end of the air injecting pipe (32) by virtue of pressure of air inside the ball main body (2) so as to be secured thereto.
- Furthermore, the air flow-in member (31) has a connecting portion (41) and a cross-shaped wall portion (45). The connecting portion (41) has an injecting pipe fixing portion (42) which is formed into a substantially circular cylindrical shape and into which the end portion of the air injecting pipe (32) is inserted to be fixed in place and a space defining portion (44) which defines a moving space (48) which is a space in which the spherical valve (33) is disposed, and the cross-shaped wall portion (45) is positioned at an inner end portion of the connecting portion (41) and has a wall which is formed into the shape of a cross, so that air flow paths (46) are formed between connecting portions where the connecting portion (41) and the cross-shaped wall portion (45) connect to each other.
- Additionally, the air injecting pipe (32) is formed into a pipe-like shape, has a semi-spherically shaped cut-out portion (54) at the inner end portion thereof and an air injecting port (51) in the enlarged portion at the outer end portion thereof, and furthermore, includes a lid portion (52) for closing the air injecting port (51).
- In addition, the air injecting port (51) of the air injecting pipe (32) is formed into the shape of a multi-staged frustum and includes on an outer circumferential edge thereof a projecting line (53) which is to be locked on the inner edge of the air hole (21).
- According to the aspect of the invention, the toy ball can be provided which includes the air plug which is easy to shape and manufacture the toy ball, as well as easy injection and discharge of air and which is easy to plug after air injection is completed.

toy ball 1 which constitutes a best mode for carrying out the invention is such as to be made up of a ballmain body 2 having anair hole 21 in a predetermined position and adapted to be formed into a spherical body by injecting air into an interior thereof and a hollow rod-like air plug 3 which is freely detachably mounted in theair hole 21 and which allows air to be injected while kept mounted in theair hole 21. - This
air plug 3 includes a pipe-likeair injecting pipe 32 which has an enlarged portion at an outer end portion thereof, an air flow-inmember 31 which is mounted at an inner end portion of theair injecting pipe 32 which is positioned inside thetoy ball 1 and which has a space in an interior thereof, and aspherical valve 33 which is inserted into the space in the air flow-inmember 31 in such a manner as to be sorbable movable state to a distal end of theair injecting pipe 32 by virtue of pressure of air inside the ballmain body 2 so as to be secured thereto. - In addition, the air flow-in
member 31 has a connectingportion 41 and across-shaped wall portion 45. The connectingportion 41 has an injectingpipe fixing portion 42 which is formed into a substantially circular cylindrical shape and into which the end portion of theair injecting pipe 32 is inserted to be fixed in place and aspace defining portion 44 which defines amoving space 48 which is a space in which thespherical valve 33 is disposed, and thecross-shaped wall portion 45 is positioned at an inner end portion of the connectingportion 41 and has a wall which is formed into the shape of a cross, so thatair flow paths 46 are formed between connecting portions where the connectingportion 41 and thecross-shaped wall portion 45 connect to each other. - Additionally, the
air injecting pipe 32 is formed into a pipe-like shape, has a semi-spherically shaped cut-outportion 54 at the inner end portion thereof and anair injecting port 51 in the enlarged portion at the outer end portion thereof, and furthermore, includes alid portion 52 for closing theair injecting port 51. In addition, theair injecting port 51 of theair injecting pipe 32 is formed into the shape of a multi-staged frustum and includes on an outer circumferential edge thereof projectinglines 53 which are to be locked on an inner edge of theair hole 21. - Hereinafter, an embodiment of the invention will be described based on the drawings. As is shown in
FIG. 1 , atoy ball 1 of the invention is made up of a ballmain body 2 which is formed of a stretchable member such as a vinyl chloride resin and which has anair hole 21 in a predetermined position and anair plug 3 which is freely detachably mounted in thisair hole 21. - This
air plug 3 is made not only to prevent the leakage of air from theair hole 21 but also to allow air to be injected into the inside of the ballmain body 2 therethrough, and as is shown inFIG. 2 , theair plug 3 includes a pipe-likeair injecting pipe 32 which has an enlarged portion at an outer end portion thereof which lies to face outwards of thetoy ball 1, an air flow-inmember 31 which is mounted at an inner end portion of theair injecting pipe 32 and which has a space in an interior thereof, and aspherical valve 33 as shown inFIG. 3 which is inserted into the space in the air flow-inmember 31 in such a manner as to be sorbable movable state to a distal end of theair injecting pipe 32 by virtue of pressure of air within the ballmain body 2 so as to be fixed thereto. - As is shown in
FIGS. 2 and 3 , theair injecting pipe 32 is formed into a pipe-like shape and has a semi-spherically shaped cut-outportion 54 at the inner end portion thereof and anair injecting port 51 in the enlarged portion at the outer end portion thereof, and furthermore, includes alid portion 52 adapted to close theair injecting port 51. Theair injecting pipe 32 also has in a predetermined position on an outer circumferential edge thereof afixing projection 55 which is made to be locked in afixing recess 43 on an air flow-inportion 31, which will be described later. In addition, theair injecting port 51 of theair injecting pipe 32 is formed into the shape of a multi-staged frustum and includes projectinglines 53 adapted to be locked on an inner edge of theair hole 21. - In addition, the air flow-in
member 31 has a connectingportion 41 and across-shaped wall portion 45, and this connectingportion 41 is formed into a substantially circular cylindrical shape and has an injectingpipe fixing portion 42 into which the end portion of theair injecting pipe 32 is inserted to be fixed in place and aspace defining portion 44 which defines amoving space 48 in an interior of which thespherical valve 33 is disposed. - This injecting
pipe fixing portion 42 is formed into a circular cylindrical shape and whose inside diameter size is substantially the same as an outside diameter of theair injecting pipe 32. The air injectingpipe fixing portion 42 includes in a predetermined position on an inner surface thereof afixing recess 43 adapted to be locked on a fixing projection provided 55 on theair injecting pipe 32 and is molded integrally with thespace defining portion 44. In addition, thespace defining portion 44 is formed into a circular cylindrical shape whose inside diameter is made smaller than that of the injectingpipe fixing portion 42 and is opened at an inner end portion, so that a stepped portion is formed between the inner surface of the injectingpipe fixing portion 42 and an inner surface thereof. - In addition, the
cross-shaped wall portion 45 of the air flow-inmember 31 is positioned at an inner end portion of the connectingportion 41 and is molded integrally with thespace defining portion 44 with a wall thereof formed into the shape of a cross, so thatair flow paths 46 are defined between connecting portions where the connectingportion 41 and thecross-shaped wall portion 45 connect to each other. Theseair flow paths 46 are defined by spaces which are formed outwardly of an intersecting portion where respective wall components of thecross-shaped wall portion 45 intersect each other and inside the opening at the inner end portion of thespace defining portion 44. - In the toy ball configured as has been described heretofore, when the inner end portion of the
air injecting pipe 32 is tightly fitted in the injectingpipe fixing portion 42 of the air flow-inportion 31, the inner end portion of theair injecting pipe 32 is locked at the stepped portion between the injectingpipe fixing portion 42 and thespace defining portion 44, and the fixing recess 43 and thefixing projection 55 are allowed to mesh with each other. Because of this, the air flow-inmember 31 and the injectingpipe fixing portion 42 can be fixed together airtightly and strongly. In addition, since an outer circumferential edge of the air flow-inportion 31 is formed larger in diameter than the outer circumferential edge of theair injecting pipe 32, a stepped portion is formed in the vicinity of a connecting portion between the outer circumferential edge of the air flow-inmember 31 and the outer circumferential edge of theair injecting pipe 32, whereby the outside diameter of theair injecting pipe 32 can be increased in the position of the inner end portion thereof. - The
spherical valve 33 is formed from a resin which is light enough to be moved by air and is positioned in themoving space 48 which is defined by thespace defining portion 44 and the cut-outportion 54 formed at the inner end portion of theair injecting pipe 32, so that thespherical valve 33 is operated by virtue of pressure of air to move towards theair injecting pipe 32 side or thecross-shaped wall portion 45 side. - Then, in the
air plug 3, when air is injected into the ballmain body 2, as is shown inFIG. 5 , thespherical valve 33 moves towards an inner end portion of themoving space 48 by virtue of pressure of air injected from theair injecting pipe 32 and its own weight, whereby the air injected from theair injecting pipe 32 flows along a circumferential edge of thespherical valve 33 and enters an interior of the ballmain body 2 from theair paths 46 defined between the opening in the inner portion of theair defining portion 44 and thecross-shaped wall portion 45. - In addition, when the injection of air is stopped, as is shown in
FIG. 6 , thespherical valve 33 is moved to an outer end portion of themoving space 48 by virtue of internal pressure inside the ballmain body 2 so as to close the opening in the inner end portion of theair injecting pipe 32, whereby thespherical valve 33 constitutes a plug which prevents the leakage of air from the interior of the ballmain body 2 to the exterior thereof, thus the leakage of air from theball 1 being able to be prevented. - Furthermore, air can be prevented from escaping from an outer end portion of the
air injecting port 51 by fitting thelid portion 52 in the outer end portion of theair injecting port 51, whereby the leakage of air from thetoy ball 1 can be prevented both by thespherical valve 33 and thelid portion 52. - Next, a method of using the
toy ball 1 of the embodiment will be described. Since thetoy ball 1 is such as to be inflated to be played with, air needs to be injected into the interior thereof. When air is so injected, firstly, the air flow-inportion 31, which constitutes a distal end portion of theair plug 3, is inserted into theair hole 21, and air is blown into the ballmain body 2 from theair injecting port 51 of theair plug 3 which is held between the lips. As this occurs, although air can be blown into the ballmain body 2 with theair plug 3 inserted deeply into the ballmain body 2, since it is easy to hold theair injecting port 51 between the lips where only the distal end of theair plug 3 is inserted into the ballmain body 2 so as to inject air as using a straw, the injection of air is facilitated. - When the injection of air is completed, the
air injecting port 51 is released from the lips and theair plug 3 is pushed into the ballmain body 2 to a root portion thereof, so that an outer circumferential edge of theair injecting port 51 of theair plug 3 is locked with the inner edge of theair hole 21 and thelid portion 52 is tightly fitted in theair injecting port 51. The leakage of air from theair hole 21 can be prevented by bringing the outer circumferential edge of theair injecting port 51 into locking engagement with the inner edge of theair hole 21, and furthermore, the leakage of air can be prevented further tightly by covering theair injecting port 51 with thelid portion 52. - On the other hand, when the air so injected is discharged from the ball
main body 2, since, by removing theair plug 3 from theair hole 21, there exists nothing covering theair hole 21, air can easily be discharged. In addition, when air is discharged, since theair injecting port 51 constitutes the enlarged portion of theair injecting pipe 32, air can be discharged by removing only theair injecting port 51 which is locked in theair hole 21 in the ballmain body 2. - According to the
toy ball 1 of the embodiment, by tightly fitting theair plug 3 which allows for air injection in theair hole 21 in the ballmain body 2, not only can the leakage of air be prevented but also the injection of air can be facilitated. - In addition, since the
spherical valve 33 is disposed in the interior of theair plug 3, so that after the injection of air is completed, thespherical valve 33 so disposed closes the inner end portion of theair injecting pipe 32 by virtue of the internal pressure of the ballmain body 2, the plug does not have to be place in such a manner as to tightly close theair hole 21 immediately after the completion of injection of air, and hence, the placement of theplug 3 in theair hole 21 can be facilitated. - Furthermore, since the
air injecting port 51 of theair injecting pipe 32 can be covered by thelid 52, theair injecting port 51 can be so covered while thespherical valve 33 closes theair injecting pipe 32, the leakage of air can be prevented. - In addition, since the ball
main body 2 of thetoy ball 1 only has to include theair hole 21, the air plug does not have to be molded integrally therewith, this facilitating the manufacture of thetoy ball 1.
