Definitions

  • novel invalid walker of the instant invention which will be seen to comprise a frame means designed for supporting and steadying the user thereof, the frame means incorporating a plurality of downwardly depending legs including at least one pair of legs constituted by a front and a rear leg each of adjustable length in typical fashion. Means are provided for coupling together the front and rear leg of the pair in a fashion such that relative shortening of one leg simultaneously effects relative lengthening of the other leg.
  • a locking means is provided disposed in position on the frame to enable an actuation thereof by the user to lock the front and rear leg pair at any desired relative length, release of the locking means enabling adjustment of the relative lengths of a front and rear leg pair simply through a shifting of the users weight on the support frame.
  • FIG. 2 is a side elevational view of the walker of the instant invention depicting its utilization in ascending a staircase;
  • the novel invalid walker of the instant invention will be seen to comprise a frame means generally designated by reference numeral 10 which incorporates a plurality of downwardly depending legs generally designated by reference numeral 12, such legs including at least one pair of legs constituted by a front and a rear leg, each of adjustable length.
  • a first pair of legs comprising front leg 14 and rear leg 16 is provided, as is a second pair of legs constituting front leg 18, and rear leg 20. From the standpoint of providing a stable support surface, however, it should be recognized by those skilled in the art that three or more legs are required.
  • valve housing 56 such as at locations 62 and 64 to communicate with the interior of the tubular frame member 22, which interior is, as afore-mentioned, contemplated to be filled with a hydraulic fluid.
  • valve means 52 As well as valve means 54 which is identical thereto, forms no part of the instant invention and may be modified as desired.
  • the important criterion herein is that the valve means, when actuated, must allow flow of hydraulic fluid through the tubular frame members and, the valve means in a non-actuated position thereof, must block and stop such flow.
