Abstract

A toy wheel formed with a balloon tire and hub is disclosed in which the tire can be inflated with a valve mechanism contained within the hub of the wheel. The hub is an assembly of hub and cap members which are interlocked together. The tire is a balloon with a single central opening at one end which is received over the hub, and the opposite end of the balloon is captured between the interlocked hub and cap members. The inflation valve comprises an air passageway through the hub member which is surrounded by a valve seat on its inside end. The valve seat is intersected with at least one axial slot along the inside end of the hub member to provide a release air passageway. The valve seat is preferably sealed by a sealing portion of the balloon. A pin with an enlarged diameter head is received in the air passageway to provide a valve operator which, when depressed, lifts the sealing portion of the balloon off the valve seat and releases the air pressure through the axial slot. In another embodiment, the valve operator can be provided with a valve member and a spring to bias it closed, against the valve seat on the hub member.

Claims

1. A toy tire assembly comprising:

(a) an elastomeric balloon having a single central opening at one end;

(b) a hub member having a peripheral rim about one end, with its opposite end received in said balloon and with said single central opening of said balloon seated against said peripheral rim;

(c) a cap member received over the outside surface of the opposite end of said balloon from said central opening, and cooperative engagement means between said opposite end of said hub member and said cap member, forming a hub assembly of said cap member removably interlocked to said hub member with said opposite end of said balloon engaged therebetween;

(d) a through passageway communicating from the outside of said hub, through said hub to the interior of said balloon; and

(e) valve means operatively seated in said through passageway to seal the interior of said balloon.

2. The toy tire assembly of claim 1 wherein said valve means includes a sealing face on an inside surface of said hub which surrounds said through passageway.

3. The toy tire assembly of claim 2 wherein said valve means also includes a valve member mounted in said through passageway distally carrying a valve seat member with resilient means to bias said valve seat member against said scaling face on said hub member.

4. The toy tire assembly of claim 3 wherein said through passageway comprises a through bore and a communicating slot in said hub member to provide an air passageway from said through bore to the interior of said balloon.

5. The toy tire assembly of claim 2 wherein said valve means comprises said sealing face on said hub member surrounding said through passageway, and the inside surface of said balloon which is received in sealing engagement over said sealing face.

6. The toy tire assembly of claim 5 wherein said valve means includes a valve operator formed by a shaft slidably received in said through passageway with its inside end bearing against said inside surface of said balloon and operative to lift said inside surface of said balloon off said sealing face.

7. The toy tire assembly of claim 6 wherein said through passageway has an enlarged diameter counterbore in said through passageway and said valve operator has an enlarged head seated in said counterbore, thereby capturing said valve operator in said hub assembly.

8. The toy tire assembly of claim 7 wherein said valve operator projects from said hub to provide lever means for releasing the inflation pressure of said tire during operation of a toy vehicle supporting said tire, thus simulating blowouts.

9. The tire of claim 5 including at least one axial slot along the opposite end of said hub, and intersecting said sealing face to provide an air passageway between the interior of said balloon and said through passageway when the inside portion of said balloon is lifted from said annular sealing face.

10. The tire of claim 1 wherein said cooperative engagement means comprise male and female interlocking means on said opposite end of said hub member and said cap member.

11. The tire of claim 1 wherein said opposite end of said hub member is cylindrical and said cap has a cylindrical sleeve portion which is received over said cylindrical, opposite end of said hub member.

12. The tire of claim 11 including snap engagement means between said hub member and said cap.

13. The tire of claim 12 wherein said snap emgagement means comprises an annular groove about said hub and cooperative annular rim about the inside of said sleeve portion of said cap.

14. The toy tire assembly of claim 13 wherein said hub has at least one axial slot which intersects said sealing face to provide an air passageway between the interior of said balloon and said through passageway when the inside portion of said balloon is lifted from said annular sealing face.

15. The tire of claim 1 wherein the opposite end of said hub member has an annular end groove surrounding said passageway, and said cap member has a sleeve end which is received in said annular end groove, stretching said sealing portion of said balloon therebetween.

16. The tire of claim 15 including an annular groove about the outer wall of said cap member and an interlocking annular rim about the inside end of said hub member, thereby providing interlocking means between said cap and hub members.

17. The toy tire assembly of claim 16 wherein said valve means includes a valve operator formed by a shaft slidably received in said through passageway with its inside end bearing against said inside surface of said balloon and operative to lift said inside surface of said balloon off said annular sealing face.

18. The toy tire assembly of claim 16 wherein said through passageway has an enlarged diameter counterbore on the inside end of said hub and said valve operator has an enlarged head seated in said counterbore, thereby capturing said valve operator in said hub assembly.

19. The toy tire assembly of claim 18 wherein said valve operator projects from said hub to provide lever means for releasing the inflation pressure of said tire during operation of a toy vehicle supporting said tire, thus simulating blowouts.

20. The toy tire assembly of claim 5 wherein said valve means also includes a cap valve operator moveably mounted in said cap member and projecting therethrough with an enlarged head received in said cap member and fixedly secured to the outside surface of said balloon opposite said sealing face of said hub member.

21. The toy tire assembly of claim 20 wherein said valve means also incluses a hub valve operator slidably received in said through passageway of said hub member with an end received in said hub member and interconnected to said cap valve operator, with the said balloon secured therebetween.

22. The toy tire assembly of claim 21 wherein said cap valve operator is slidably received in a through bore in said cap member.

23. The toy tire assembly of claim 21 wherein said cap valve operator is pivotally received in said cap member.

24. The toy tire assembly of claim 1 wherein said peripheral rim comprises first and second, stepped diameter rims with at least one axial rim slot through and slightly beyond said outermost rim, whereby said central opening of said balloon seats against the innermost of said two rims for normal inflation and expands to seat against the outermost of said rims when the inflation pressure exceeds a predetermined amount, thereby venting the interior of said balloon through said axial rim slot.
