Abstract
Abstract A portable seat for mounting on an invalid walker enabling a walking invalid to sit and rest until strength is recovered sufficiently to continue walking. The seat comprises a rectangular, foldable sheet of material of sufficient strength to support a person. The seat can be readily attached to the walker for seating to rest and readily detached for carrying on the person in pocket or purse for walking. The seat is adjustable in one or more respects and can be mounted on the more complex of common walkers, such as some foldable swinging walkers, without making holes in or structural changes to frame members. Four hooks are detachably connected to respective frame members by means of ordinary hose clamps. A metal ring is attached to the sheet at each corner thereof and the sheet is attached to the walker by placing each ring on a respective hook. The seat can be manufactured from readily available common parts and installed using common skills and tools.
