| Abstract: |
A walker which comprises a pair of interconnecting side frames. Each of the side frames includes a pair of upright legs and a hand grip bar connecting upper end portions of the legs. A caster is adapted to support each leg. A spring is mounted in association with each caster to urge the leg associated therewith to a raised position in which the lower end of the associated leg is spaced above a surface on which the casters run. The springs yield when weight is applied to the bars to cause the lower ends of the legs to engage the supporting surface to lock the walker in position.

First Claim:
Show all 5 claims |
Having described my invention, what I claim as new and desire to secure by letters patent is:
1. A walking aid device which comprises horizontal hand rails and vertical support members connected by lateral stabilizing means to form a rigid frame, there being an open space between the hand rails for a patient with hands on the hand rails and feet supported by a supporting surface, the lower extremity of the vertical support members incorporating rubber feet that can contact the supporting surface in a rigid and non-sliding fashion, said walking aid device incorporating casters which travel on the supporting surface in quadraped manner that are pivotally mounted to the frame, longitudinal stabilizing tubes horizontally disposed near the lower ends of said vertical support members, said longitudinal stabilizing tubes extending outwardly past the confines of the vertical members to form caster mounting means in such a manner as to place caster wheel bearing points outside the columnar load path of the vertical support members and spring means between the casters and said frame, so that the frame is carried on the casters when vertical load is absent, said spring means being relatively weak insofar as the springs will carry slightly more than the frame's structural weight so that the patient can load the frame to bring the rubber feet into periodic contact with the floor providing a firm means of support when the frame is loaded by the patient, the rubber feet engaging the supporting surface to prevent advance of the device when the frame is loaded.
