Safety rolling invalid walker |
摘要 |
A rolling invalid walker has normally locked wheels and one or more hand controls for disengaging the locks to permit unlimited rolling. A preferred embodiment comprises a walker frame with four legs and wheels. The two front wheels are normally locked, and a pair of hand controls are provided for disengaging the locks with minimal pressure. The hand controls are coupled together by a horizontal tie rod so that the wheels can be unlocked by either or both controls and so that emergency pressure on either control will lock the wheels.
