Abstract
A stroller wheel device includes a wheel, a frame-connecting member, a wheel-connecting arm, and a resilient member. The frame-connecting member includes at least one first pressing portion. The wheel-connecting arm includes upper and lower ends connected respectively and pivotally to the frame-connecting member and the wheel, and at least one second pressing portion spaced apart from the first pressing portion. The resilient member is disposed between and abuts against the first and second pressing portions. When the wheel-connecting arm rotates relative to the frame-connecting member, the first and second pressing portions move toward each other to compress the resilient member.
Claims24
A stroller wheel device comprising:
- a wheel;
- a frame-connecting member including at least one first pressing portion;
- a wheel-connecting arm including upper and lower ends connected respectively and pivotally to said frame-connecting member and said wheel, and at least one second pressing portion spaced apart from said first pressing portion;
- and
- a resilient member disposed between and abutting against said first and second pressing portions such that, when said wheel-connecting arm rotates relative to said frame-connecting member, said first and second pressing portions move toward each other to compress said resilient member;
- wherein said frame-connecting member includes a sleeve connected pivotally to said wheel-connecting arm, a pressing ring disposed between said frame-connecting member and said wheel-connecting arm, said pressing ring including said first pressing portion at an end thereof facing said second pressing portion, said pressing ring being connected to said wheel-connecting arm in such a manner to be driven by said wheel-connecting arm to rotate to thereby move toward said second pressing portion.
