Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
89 words
An eccentric wheel of a bicycle comprising a wheel body, a pair of tracks disposed in said wheel body and arranged in parallel with each other and each including at least one hole formed therein, a block slidably engaged between said tracks for supporting a wheel axle of said bicycle, a pair of pins slidably engaged in said block and extendible outwards of said block for engagement with said holes of said tracks, and means biased between said pins for biasing said pins outwards to engage with said holes.
Claim 2
Dependent Claim
89 words
An eccentric wheel of a bicycle comprising a wheel body, a pair of tracks disposed in said wheel body and arranged in parallel with each other and each including at least one hole formed therein, a block slidably engaged between said tracks for supporting a wheel axle of said bicycle, a pair of pins slidably engaged in said block and extendible outwards of said block for engagement with said holes of said tracks, and means biased between said pins for biasing said pins outwards to engage with said holes.
Claim 3
Dependent Claim
48 words
An eccentric wheel according to claim 1, wherein each of said tracks includes a rib formed longitudinally thereon, said block includes a pair of recesses oppositely formed therein for slidable engagement with said ribs of said tracks such that said block is guided to slide along said tracks.
Claim 4
Dependent Claim
28 words
An eccentric wheel according to claim 2, wherein said ribs have a length shorter than that of said tracks such that said block is engageable between said tracks.
Claim 5
Dependent Claim
37 words
An eccentric wheel according to claim 1, wherein said block includes a pair of protrusions formed thereon with a notch formed therebetween, each of said protrusions includes an aperture formed therein for slidably receiving said pins respectively.
Claim 6
Dependent Claim
45 words
An eccentric wheel according to claim 4, wherein said means biased between said pins is a spring disposed in said notch and includes a pair of legs fixed to said pins respectively, whereby, said pins are disengaged from said holes when said spring is compressed.
Claim 7
Dependent Claim
12 words
An eccentric wheel according to claim 5, wherein said spring is omega-shaped.
Claim 8
Dependent Claim
129 words
An eccentric wheel of a bicycle comprising a wheel body, a pair of tracks disposed in said wheel body and arranged in parallel with each other and each including at least two holes formed therein, a block slidably engaged between said tracks for supporting a wheel axle of said bicycle, a pair of pins slidably engaged in said block and extendible outwards of said block for engagement with said holes of said tracks, and biasing means biased between said pins for biasing said pins outwards to engage with one of said holes of each of said tracks, whereby, said pins are disengaged from said holes when said biasing means is compressed, and are biased outwards to engage with other holes when said pins are aligned with said other holes.
Claim 9
Dependent Claim
129 words
An eccentric wheel of a bicycle comprising a wheel body, a pair of tracks disposed in said wheel body and arranged in parallel with each other and each including at least two holes formed therein, a block slidably engaged between said tracks for supporting a wheel axle of said bicycle, a pair of pins slidably engaged in said block and extendible outwards of said block for engagement with said holes of said tracks, and biasing means biased between said pins for biasing said pins outwards to engage with one of said holes of each of said tracks, whereby, said pins are disengaged from said holes when said biasing means is compressed, and are biased outwards to engage with other holes when said pins are aligned with said other holes.
Claim 10
Dependent Claim
48 words
An eccentric wheel according to claim 7, wherein each of said tracks includes a rib formed longitudinally thereon, said block includes a pair of recesses oppositely formed therein for slidable engagement with said ribs of said tracks such that said block is guided to slide along said tracks.
Claim 11
Dependent Claim
28 words
An eccentric wheel according to claim 8, wherein said ribs have a length shorter than that of said tracks such that said block is engageable between said tracks.
Claim 12
Dependent Claim
37 words
An eccentric wheel according to claim 7, wherein said block includes a pair of protrusions formed thereon with a notch formed therebetween, each of said protrusions includes an aperture formed therein for slidably receiving said pins respectively.
Claim 13
Dependent Claim
45 words
An eccentric wheel according to claim 10, wherein said means biased between said pins is a spring disposed in said notch and includes a pair of legs fixed to said pins respectively, whereby, said pins are disengaged from said holes when said spring is compressed.
Claim 14
Dependent Claim
12 words
An eccentric wheel according to claim 11, wherein said spring is omega-shaped.
