摘要:
A compressible wheel tip for a walking aid that restricts rolling when a force is applied down on the walking aid. The tip may have a compressible wheel configured to deform under an applied pressure and thereby restrict shifting or rolling of the wheel. The compressible wheel may include rigid spokes and a compressible material forming an arcuate perimeter between the spokes to define a wheel shape. The compressible material may be a resilient elastomeric material adapted to deform under an applied force and return to its original shape when the force is no longer applied. The spokes may be formed of plastic or metal, or formed of the same material as the spokes and structured to better resist deformation.
