Abstract
A wheel assembly includes a connecting member connected to a frame of a baby walker or stroller, thereby allowing the upper shield to rotate relative to the frame. The upper shield further includes two opposite walls defining an upper compartment therebetween, the opposite walls including a pair of aligned axle receiving holes. A lower shield is connected to the upper shield and includes a lower compartment that aligns with the upper compartment. A wheel is rotatably received in the upper compartment and a lower compartment and has a lower end extended beyond the lower compartment. An axle is extended through an axle hole of the wheel and the axle receiving holes of the upper shield. The upper shield and the lower shield cover the axle hole of the wheel and the axle to prevent entrance of alien objects.
Claims4
A wheel assembly for a child's wheeled gear, comprising:
- an upper shield including connecting means for pivotal connection to a frame of a child's wheeled gear to thereby allow the upper shield to rotate relative to the frame, the upper shield including a pair of spaced opposing walls defining an upper compartment therebetween, the pair of walls having a pair of aligned axle receiving holes formed therein;
- a lower shield connected to the upper shield, the lower shield having a lower compartment formed therein and disposed in aligned relationship with the upper compartment and an annular stop extending from an outer periphery thereof and adapted to substantially prevent the wheel assembly from rolling past an obstacle;
- a wheel having an axle hole formed therethrough and being rotatably received in the upper compartment and the lower compartment, the wheel having a portion thereof extending from the lower compartment external the lower shield;
- and,
- an axle passing through the axle hole of the wheel and engaged with the pair of axle receiving holes.
A wheel assembly for a child's wheeled gear, comprising:
- an upper shield including connecting means for pivotal connection to a frame of a child's wheeled gear to thereby allow the upper shield to rotate relative to the frame, the upper shield having an upper compartment formed therein;
- a lower shield connected to the upper shield, the lower shield including a pair of spaced opposing walls defining a lower compartment therebetween, the lower compartment being disposed in aligned relationship with the upper compartment, the pair of walls having a pair of aligned first axle receiving holes and a pair of aligned second axle receiving holes respectively formed therein, the pair of second axle receiving holes being at a level different from that of the pair of first axle receiving holes, the lower shield having an annular stop extending from an outer periphery thereof and adapted to substantially prevent the wheel assembly from rolling past an obstacle;
- a wheel having an axle hole formed therethrough and being rotatably received in the upper compartment and the lower compartment, the wheel having a portion thereof extending from the lower compartment external the lower shield;
- and,
- an axle passing through the axle hole of the wheel and selectively engaged with one of the pair of first axle receiving holes or the pair of second axle receiving holes for adjusting a size of the portion of the wheel extending from the lower compartment to accommodate different surface contours.
