Abstract

A roller skate wheel includes an outer wheel body defining a receiving space and having an inner wall formed with a first annular flange and a second annular flange spaced from each other, an inner tire received in the receiving space, a first wheel cap secured to the first annular flange, a first bearing received in a first opening defined in the first wheel cap, a second wheel cap secured to the second annular flange and securely coupled with the first wheel cap, and a second bearing received in a second opening defined in the second wheel cap.

Claims

1. A roller skate wheel comprising:

an outer wheel body defining a receiving space and having an inner wall formed with a first annular flange and a second annular flange spaced from each other, said first annular flange being formed with a plurality of first blocks spaced apart from one another and each defining a first hole;

an inner tire received in said receiving space;

a first wheel cap secured to said first annular flange, said first wheel cap being formed with a plurality of first lugs spaced apart from one another, each said first lug extending between adjacent ones of said first blocks of said first annular flange, said first wheel cap having a plurality of first positioning posts each disposed between adjacent ones of said first lugs, each of said first positioning posts extending into said first hole of one of said corresponding first blocks; and

a second wheel cap secured to said second annular flange and securely coupled to said first wheel cap.

2. The roller skate wheel as recited in claim 1, wherein said second annular flange is formed with a plurality of second blocks spaced from each other and each defining a second hole, and said second wheel cap is formed with a plurality of second lugs spaced from each other and each located between adjacent ones of said second blocks of said second annular flange, and a plurality of second positioning posts each formed between adjacent ones of said second lugs and each extending through said second hole of one of said second blocks.

3. The roller skate wheel as claimed in claim 2, wherein each of the first lugs is located between the two adjacent second lugs and defines a first recess to receive the respective second positioning post therein, and each of the second lugs is located between the two adjacent first lugs and defines a second recess to receive the respective first positioning post therein.

4. The roller skate wheel as claimed in claim 1, wherein the first wheel cap defines a first opening therein, and the roller skate wheel further comprises a first bearing received in the first opening.

5. The roller skate wheel as claimed in claim 1, wherein the second wheel cap defines a second opening therein, and the roller skate wheel further comprises a second bearing received in the second opening.

6. A roller skate wheel comprising:

an outer wheel body defining a receiving space and having an inner wall formed with a first annular flange and a second annular flange spaced from each other;

an inner tire received in said receiving space;

a first wheel cap secured to said first annular flange; and

,

a second wheel gap secured to said second annular flange and securely coupled to said first wheel cap

said first annular flange being formed with a plurality of first blocks spaced from each other and each defining a first hole, said second annular flange being formed with a plurality of second blocks spaced from each other and each defining a second hole, said first wheel cap being formed with a plurality of first lugs spaced from each other each located between adjacent ones of said first blocks of said first annular flange, and each defining a first receiving passage, a plurality of first threaded holes being defined in said first wheel cap and each located between adjacent ones of said first lugs, said second wheel cap being formed with a plurality of second lugs spaced from each other each located between adjacent ones of said second blocks of said second annular flange, and each defining a second receiving passage, a plurality of second threaded holes being defined in said second wheel cap and each located between adjacent ones of said second lugs, a plurality of first nuts each received in said second receiving passage of a corresponding one of said second lugs, a plurality of second nuts each received in said first receiving passage of a corresponding one of said first lugs, a plurality of first bolts each extending through a corresponding one of said first threaded holes and each engaged with a corresponding one of said first nuts, and a plurality of second bolts each extending through a corresponding one of said second threaded holes and each engaged with a corresponding one of said second nuts.
